It's a decent arduino shield

For Arduino GRBL to DB25 CNC Shield Kit

It definitely works as advertised, and at a decent price, too. One thing that's definitely worth noting is that if you're intending to use limit switches, get hold of some small ceramic capacitors and resistors, or buy the pre-made ones used on 3D printers - you're going to need the filtration on the limit switch signals. Trust me on this. I wish it had been mentioned in the documentation, but since this isn't a GRBL-specific product, I'm thinking that's probably an unfair request on my part.

With regards to the 3 stars on shipping - this is not the fault of the sender, this is entirely down to the whole US to UK shipping ordeal that's been compounded by COVID and probably Brexit as well.

Sometimes the simplest thing makes a big difference.

For Arduino GRBL to DB25 CNC Shield Kit

Many years ago I used to wire the DB 25 by hand for CNC machines. Back in 2018 I bought one of these for my 3040 mill and it worked great. I 3D printed a case for it I downloaded from thingiverse and haven't thought about it since. so simple and It just works. I just got another cnc control board with a DB25 input so I bought a second card. Had to double check this page to make sure I put the connector on the right side before I soldered it together.

Great Board, clean design with quality etching.

For ST25 - Arduino GRBL Screw Terminal Breakout Board

Did find the white silk-screen a tad hard to follow.
It would help if http://KCLinear.com/ST25 included the following (which does format pretty with monospace font)

Variable Spindle PWM LZ PZ Pulse Z
Y Limit LY DZ Direction Z

X Limit LX EZ Enable/Disable Z**
Ground G G Ground


Spindle Direction SD PY Pulse Y
Z Limit SE DY Direction Y

Reste/Abort* RA EY Enable/Disable Y**
Feed Hold* FH G Ground


Cycle Start/Resume* CS PX Pulse X
Coolant Enable CE DX Direction X

Reserved R EX Enable/Disable X**
Probe P G Ground


** enable/disable are tied together on X,Y,Z

Over 6 months later and it still hasn't arrived.

For Arduino GRBL to DB25 CNC Shield Kit

This is an updated review. My order has not arrived, but Ron has offered a refund or resend, unfortunately I did not see his messages so I have ignored it for the last 2 months. Sorry Ron. Thanks for your assistance.

Arrived quickly in UK and looks well made.

For Arduino GRBL to DB25 CNC Shield Kit

Shipped quickly to the UK and looks well made. I intend to use this to use with an Arduino Uno to interface to an old CNC machine that currently has a 25way "parallel port" connector. As i have not had time to try it yet so i don't know if i will have to modify the wiring a bit but it is easier than starting from scratch on prototype board

reasonable price

For Arduino GRBL to DB25 CNC Shield Kit

This is the 2nd pcb I've gotten, to interface to HobbyCnc Pro board,
Card 1 I did a lot of path cutting and rewiring , to get it to work.

I not sure if all the cutting and rewiring was needed , Is why I ordered the
2nd pcb, I've been unable to find a good schematic of the pcb,
Its still sitting in the box, waiting another try!

Response from Ron | Nov. 18, 2020
There is no schematic because there are no components (besides pins and connectors).
However, you can find the pin mapping in the instructions http://kclinear.com/g25/

Thank you

No sign of it...

For Arduino GRBL to DB25 CNC Shield Kit

Can't rate a product I didn't get, so this review is on shipping and communications.

2 months and track & trace says it hasn't moved, so now assuming it has been lost. Wouldn't use lockdown as excuse since I've had packages from mainland China get here in 3-4 weeks after ordering. When asked for help, I got quoted a case number I can't review or get an answer on, and pretty much no other interest.

Enjoy the donation.

Great board, great instructions. Sadly didn't work for me.

For Arduino GRBL to DB25 CNC Shield Kit

Found out after I got it that my cnc uses a very 'nonstandard' pin-out. The board is great, I think it would be excellent if I could have used it.

One suggestion if you're going to update it, would be to allow some form of remapping pins for any specific db25 based board. The best example I can give for that is that my particular CNC board has this pin-out:

(they call the A motor C I'm guessing to reduce confusion about the A+ A- of the coils?)
Pin 1: X - Dir
Pin 2: Spindle Motor
Pin 3: Z - Step
Pin 4: X - Enable
Pin 5: Z and C - Enable
Pin 6: Z - Dir
Pin 8: C - Dir
Pin 9: C - Step
Pin 14: Y - Step
Pin 15: Z - Enable
Pin 16: X - Step
Pin 17: Y - Enable

this is from their pin-out, but I think due to that being on their side, it has to be 'reversed' for the other side. I.E. Pin 1 = Pin 25 on the breakout board. I was just going to manually do some jumpering but the pins something like 18-25 or so are all connected on the board and can't be used individually.

Again, I get that this was designed for a specific pin-out, and I'm getting a workaround together, just an idea for a potential future version of the board that allows more versatility.

Thanks anyway, sad I can't use it :)

Works but requires DIY skills

For GRBL to DB25 CNC Shield Kit With Arduino UNO R3

I received the PCB - high quality -, a female DB25 connector and a row of pins, plus an Arduino Uno clone. I think this product could be improved by 1) providing a better Arduino clone (using Atmel serial chip instead of CH340 and with GRBL already flashed); 2) providing a box (I designed one and published it here https://www.thingiverse.com/thing:4129045) ; 3) providing additional components (or at least diagrams) to use additional features of PCB such as monitoring LEDs and resistances and PWM power driver

1. Fair enough.
2. I do have one. https://www.thingiverse.com/thing:1463398 (I will add this to the description and documentation)
If you don't mind, I will link to yours as well.
3. All great ideas.
Thanks for the feedback.

New life for old lathe

For Arduino GRBL to DB25 CNC Shield Kit

Nothing short of a miracle! My old CNC lathe came back to life after years of slumber, brought on by the demise of the LPT 'printer port'. Now she lives***** Thanks Guys!

Well made, and surprisingly easy to bring up

For Arduino GRBL to DB25 CNC Shield Kit

I was expecting to have to do a lot of Grbl configuration to get this board to wiggle the right pins on the DB25, but I was surprised to learn that the default build worked.

I used this to convert a Chinese 3020 CNC to Grbl. Apparently, mine didn't have the "common" DB25 mapping, so my X axis wasn't working. A bit of debugging determined that X and A were swapped, so the simplest fix was to swap them on the breakout board, and now I have the common mapping that works directly with this shield. Awesome!

ST25 - Arduino GRBL Screw Terminal Breakout Board

For ST25 - Arduino GRBL Screw Terminal Breakout Board

The ST25 - Arduino GRBL Screw Terminal Breakout Board is easy to assemble with minimal soldering skills. Fits on the Arduino UNO well with little fuss. I'm using the ST25 - Arduino GRBL Screw Terminal Breakout Board to power the two stepper motors on my CNC lathe. Using GRBL 1.1 the ST25 - Arduino GRBL Screw Terminal Breakout Board is laid out for simple wiring to the stepper drivers. I'm going to be repowering my CNC mill using GRBL 1.1 and getting rid of Mach3 so I'll be ordering another of the ST25 - Arduino GRBL Screw Terminal Breakout Boards for that project. Because of the very good quality of the ST25 - Arduino GRBL Screw Terminal Breakout Board I can highly recommend it to anyone who is going to use Arduino and GRBL to power their machines. I say thanks for a great product and I'll be ordering another soon.

Good product

For Arduino GRBL to DB25 CNC Shield Kit

Good product with some minor errors in the documentation. In the overview of pinouts the GRBL layout column, dir and step is switched.

Just for reference: I have the CNC 3040 with the "new" blue control box. Here the A axis in on DB25 pin 2/3 and X on 16/17.

Clever little board for those Parallel port CNC's you find

For Arduino GRBL to DB25 CNC Shield Kit

Board arrived nice and quickly, shame there's zero documentation though and the seller's away on holiday currently which could be why his link at http://kclinear.com/g25/ seems to be down....

Ah well, jumped straight in with the soldering iron, taking cues from the youtube videos he's posted as to which side the components go on!
I have a spare header in the package for some reason

I'm pleasantly surprised that After a very quick solder, purchase of the correct Arduino and flashing of Grbl V1.1F....the CNC fired straight up with Chillipeppr!

No need to play with Polou style drivers and CNC shields and do lots of re-wiring now! just plug this board on the controller and voila!

Thankyou!

Board is good, but Arduino is not preprogrammed with GRBL

For GRBL to DB25 CNC Shield Kit With Arduino UNO R3

I would think the whole point of supplying an Arduino would be to supply a board preprogrammed with GRBL. Now I have to take extra time to figure out the world of AVR.

Otherwise customer service and shipping was amazing.

The GRBL to DB25 shield is just what I was looking for!

For Arduino GRBL to DB25 CNC Shield Kit

I'm building a PCB router from aluminum bar stock and surplus round steel ways and Acme lead screws. I have built similar drive boxes for my CNC'd Sherline mill and lathe. These are DB25 interfaces, driven from a PC running my STEP4 CNC driver software (15-16 year old DOS program). They run fine. This new drive box will have four G251X GeckoDrives and a DB25 interface. I will drive it either from a PC or from an Arduino running GRBL. I was about to wire up a prototype shield to interface to a DB25 cable. The shield resolves that problem. This driver box also employs a DB25 breakout board (first time I've used one), and a dimmer/ssr board (also from tindie) for spindle speed control. I have also used three switching power supplies for 24V, 12V and 5V. The 24V is for the steppers (could go up to 48V), the 5V is for the breakout board and a SSS (solid state switch). The 12V power supply is for 3D printing. I can thus run CNC (STEP4 or GRBL), Laser or 3D printing. Laser GRBR and Marlin will run as appropriate.

This shield is just what I was looking for! I bought two, one dedicated for CNC, the 2nd for a laser. Cheap enough, and I like the dedicated Arduino UNO's. For 3D printing, I'll use an Arduino Mega and a RAMPS board. I could use a RAMPS - DB25 board for that! I think I can us a piece of prototype board, solder .025" posts into it to plug into the vacated stepper driver sockets. I'll also wire up the limit switches, and E-switch (?).

Simple enough to solder up the board. I might suggest supplying or offering socket/headers for this shield to allow stacking. The pinout for the shield follows convention, although as my first Gecko driver box (G201) has the pinout for the step/dir pins different, I'll have to put in conditional code to allow my pin selections. A double row of 25 (maybe don't need all) pins with default traces that could be cut and allow some pin swaps would be nice. Put me in for one if you do it! A DB25-RAMPS board would also be welcome!

I can certainly recommend this board!

Alan
EDIT 3:53PM I just examined the GRBL to DB25 PCB, and noticed a row of holes alongside the Arduino pins. I've seen double rows of holes on boards before, but usually they're additional signals. This is a solution to my need to swap S/D pins! Some comments on these and other pads on the board would be useful in the manual.

GRBL DB25 shield

For Arduino GRBL to DB25 CNC Shield Kit

A simple but powerful shield to interface arduino uno with DB25 breakout board.
The board is professionally made, fully functional and good documented.
Working out of the box also with GRBL 1.1 version.

Good product

For Arduino GRBL to DB25 CNC Shield Kit

Fast seller, to send the product.
It board is off good quality.
The documentation is good.
But in the documentation pin A4 is not good documented, it has to be A5 this one is connected.

I wish that some of the connections were not fixed mapped, so I could connect some pins to other DB25 pins
For example:
Pin1 output spindle direction, but in some machines sometime used as PWM.
Pin 10 = reset/Estop, but sometimes used as A limit.
Pin 17 = PWM or output, but sometime used as A step
The board has the connectors on it to do this.
But then some connections must be cut, the same way as for D11 and D12
Thank You.

Well made board for use with GRBL on Arduino

For Arduino GRBL to DB25 CNC Shield Kit

This is a very nice shield for moving the Arduino pins out to a 25pin female connector (aka printer port). The board has a solder mask on the two outer layers, and a silkscreen on the upper layer. It was nice to have the option of supporting a later version of GRBL with PWM operation thru a simple modification to the board. There appears to be a discrepancy between the GRBL documentation regarding the pinouts for the stepper motors (direction and step flipped?) when compared to a LeadShine MX4660 Drive with Breakout board. I had to buzz out the shield board to see how it was wired to resolve my confusion. It would have been nice to have the schematic for the board. Instructions were quite good, and well illustrated. The board has additional prototyping areas. I intend to use one section to pull out a hard reset (for the Arduino), emergency reset (A0), hold (A1), and resume (A2) commands via switches.

Communications were listed as OK, but it should have been N/A. This was a straight purchase with no additional queries.
