Hi, what kind of mega shield I'll have to use to make it run? Are you using rams 1.4 or some custom pcb?
I made my own pcb based on a grbl shield. I had a few professionally made.
I supports 6 axis and total of 6 output relay controls Cool & mist (M7, M8, M9) R1 to R4 (M85, M86, M87, M88) All toggle on off and M89 all R? Off
I will send you a board if give me address to mail to. I will solder everything on my board but you will need the mega. I will send the Grbl firmware I use also.
I use bCNC to run my machine

Thanks! I'll be very glad to play with your board and hopefully finish my 4 axis cutter.

bCNC has been very useful but I'll probably switch to full custom on PC side.
Another note... I use all external motor drivers, not the DRV modules. Will that be an issue? If not, give me a few days to get put together and copy files, because of the holidays. I'll get mailed out and let you know when I do.
Hope it will be very useful. I have been running board for 4+ years now

Can you elaborate a bit on external motor drivers? Does it mean your board has just step/dir outputs routed to external motor controllers?
Correct.

Then I'm afraid it'll be of little use to me.
If I can ask you used it with external powerful drivers for big steppers / BLDCs or you simply had board with stepstics on it?
I did start with the small DRV modules but kept burning up. I am using NEMA23 motors for all 5 axis
I believe I may have an add-on board for the small drivers. Basically wire as Step, Dir and power from mega board to add-on DVR drivers. How many axis are you using?
Let me see what I have and I'll see if you can use it.
I am working now but will be back in a couple hours and I will check if I have what you need.

I'm doing 4 axis on 6 motors (2 axis have 2 motors in parallel and that's stretching what's possible on DVRs so anything than can handle a bit more is welcome change).
is any of the 6 relay outputs capable of PWM like standard grbl?
No, relays are on/off only
The dual motors can be parallel from wiring off mega also. Each on its own DRV and same signal from mega.
If i have 2 add-on boards with 4 motors per board, that would allow dual motor wiring

That'd be perfect. If not then single add-on board and motor windings in parallel should also be sufficient.
Yes, I actually made you 2 adaptor boards I'm am in process of soldering the mega shield.

I have all the boards ready to ship. It will take me a few days to get mailed because of my work schedule. I will let you know when the ship.
I am also sending a thumb drive that contains the diagrams, pin outs, arduino library and pre-compiled .hex files.

Sorry, my github somehow supressed notifications. thank you very much for all your help! I already started reading all docs of GRBL to hopefully be at least close to getting into your code when everything arrives.
Wow, I apologize. I have been out of town working. I will be back tomorrow and I will get mailed

Ok, slight setback... I didn't realize the shipping was so darn expensive.
I need to know how you want to proceed.
USPS has NO TRACKING AT ALL
UPS has TRACKING ALL THE WAY

I think no tracking. As far as I remember shipping costs UPS may cost few times more than entire controller
Boards on the way Estimated 7-21 days

Need anything to help understand or setup, let me know.
When parts arrive, look on USB for diagrams and GRBL setup files.

No, still fighting with customs. They can't believe I got such "industrial equipment" as a git. But should hopefully be solved within days
Wow. I hope it works out soon. Good luck.

Just let me know if I can help in any way
