Hmm, good point. I forgot that James had multiple button pushes blocked. One other thought - James also blocks many of the keys from working when things are running. If...

Good deal, glad that the replacement took care of things. After I got my system together and working, I ordered a second set of boards from James and have those...

mac, Where in the code did you make the adjustment for the feed rates? The Precision Matthews lathe has the gearbox for both Z axis feeds and cross feeds separate...

If I've measured correctly, it looks like the gearing ratio is about 1:3.3. On turn of the lead screw with the feed gearbox engaged moves the tool 0.0375", so about...

Edits removing stream of consciousness calculations that only confuse things.....

Just tested the changes in the last post and that worked perfectly. Feed rates are updated and accurate, thread rates unchanged and still accurate. Edits removing stream of consciousness calculations...

MAC, It took me some fiddling to figure out my gear ratio. There is considerable backlash through the gearbox setup, but I did something similar to what you did with...

Well, shoot. After all of that, I remembered these couple of lines in configuration.h: // Separate step and microstep settings for feed rates. Redefine these if your // lathe has...

Forgot to say, if making the above change to configuration.h, we'd leave tables.cpp as we get it from James.

My apologies, I'm posting like Robin Williams doing a stand up routine, stream of consciousness. I'm used to having these discussions standing at a whiteboard with another engineer in my...
