DIY ATC Tormach 770M EP9 Column Mount, Powder Coating and Partial Assembly

[@Nordic_Goon]

Nice build! I made a 10 tool ATC for my 440. If it's of any help, I haven't really had any issues with my linear rails on the ATC, my biggest qualm, is that I never got around to building a cover to keep chips off the tool holders. Especially since I used the factory ATC firmware as the starting point for my project, the airblast intervals aren't frequent enough to fully clear chips before a tool change.

Thanks! I plan to build the cover as I have a CNC plasma cutter to cut the material. I am using the OEM firmware i noticed it had a short air blast maybe 1 second. Will have to see if it can be changed to a longer duration.

@@iccustomsusa8048 definitely! Did you go with a pyboard? That's what I used haha. Mainly just had to remap output pins, made it a 10 tool at, instead of the 8 tool tormach normally has for the 440, and played with the stepper motor steps per revolution and stuff as I used a geared nema 17. I may rebuild mine a bit to improve it if I ever I have time, and I'd go with a larger nema 34, bigger driver and a belted pulley setup like yours. Looks great. Making am ATC was the best quality of life improvement upgrade for the tormach for sure.

@@Nordic_Goon Yes using PYboard and a custom interface PCB the PYboard badges too. Really cleans up the wiring and allows use of a small electronics box. Also I am using the Tormach "ATC connector" on the machine for my power and connection to the VFD if in the future I switch to BT

@@iccustomsusa8048 nice, I had just used the pyboard with individual components, but if I do redo the controller, I'll definitely try my hand at a custom interface board. That's something I've been wanting to dabble with.

@@Nordic_Goon In EP2 I show a little on the PCB/schematic I drew up it is relatively small for the number of in/outputs. I am on the 3rd revision after a few drafting mistakes and function additions.
