MemberActually, the motors I have are 2.8A/phase wired in parallel, 1.4A/phase wired in serial. I have them wired in serial. The only reason I bring that up is that 1.4A is significantly below the 2.5A limit, but it appears they’re still pulling more than that (or else otherwise generating waaaay too much heat). So the margin of error on my datasheet is quite significant.
Unrelated Q: is 0.93 officially released? (I’m still on edge, but might switch to .93 if it’s out.)
MemberYes, mine have both, so I can wire them either way. I didn’t get any shop time last night to double-check my config, but I should be able to make everything work with NO as the default. So you can defer my request for switch mode setting. 🙂 (And I’m looking forward to v.93 for spindle control!)
MemberI must admit I’m better on the SW side that the HW side, so I’ll probably poke around gpio.c. However, I could have sworn that I wired my existing endstops for NC and that they were functioning correctly – perhaps they were actually trigger on the switch release instead of the depress. I’ll have to double-check that when I get home. (Side note: I consider NC to be a “safer” default, since if an NC switch accidentally disconnects or otherwise fails, the system thinks it hit a stop and won’t try to run off the end. It’s less likely that a NO switch will accidentally fail closed.)
Of course, if I find out that my X and Y switch are actually operating NO, then I can just swap terminals on the switches and they should all work. 🙂
Memberalden: for what I’m planning on building, I’ll likely not be able to use PWM for spindle speed control, since I don’t plan on cracking open my router and messing around with the pot that does the speed control. But, it would be nice to have a pin or two that could trigger a relay that’s inline with the router’s power cord to control on/off. That would enable something like an EPO switch to kill the spindle and motors all at once.
