The encoders being just incremental - I have the code in the sketch monitor the encoders throughout a commanded move and verify that the commanded mot...
Hello, yes the robots DH parameter's are on line 249 in the sketch: float DHparams[6][4] = { { 0, 0, 169.77, 0 }, { -90, -90, 0, 64.2 }, {...
@joseph-puzzo I think you'll need to run the AR4 sketch with -neg pulse. Keep me posted if you have any issues.
The Stepperonline drivers (DM542T and the 320) do operate at 3.3v they are supposed to be updating the manual to show that. I assume you are running D...
The drivers I was using in the earlier versions of the AR2 did not work with PNP or common cathode so the original architecture was setup for an open ...
The J1 housing contains (2) 32009 taper roller bearings that are opposed, the J1 platform has set screws that set the tension (red arrows) against the...
The pull-up resistors weren't strong enough to be reliable over a 5 ft ethernet cable, so I opted to do three wires and pull it to ground when the swi...
Yes you can use the Mega code, I just switched to the nano on the AR4 because it was lower cost, took up less space and has more readily available ter...
@midnightoilburner This is awesome. thanks for sharing!
Wow, that looks awesome. <correction the font was "Latin">. Please feel free to share any stl or cam files here on the forum or let me know what...
Hello, just replied to your email, I do have some stock on those right now. Thank you.
@dan I'm glad its resolved. You're not the first, I to have spent countless hours (and beer) trying to solve problems due to issues I assumed to be in...
@dan when you said "12v/5v power supply for the teensy (5v)" are you using an external power supply for the teensy? I have never powered it from an e...
Ok, that's typically the first thing I look at when only the DM320 drive is working. Did you have this robot operational previously with the AR3 softw...
have you set the DM542 driver input level from 24v to 5v ? J4-is-the-only-joint-that-moves-AR3-Teensy-4.1-.avif
