for your custom robot are you using the AR3 software or the AR4 software?

Yes you can load the AR4 sketch on the 3.5 without issue. The 4.1 is just a higher performance board.

@olof-ogland I am working with @Olivier Allard at RoboDK to make the appropriate software updates. Hopefully we can get things going.

Im still waiting to hear back from RoboDK, they said they are still working on the driver but that they had some other projects come up and are delaye...

@olof-ogland can you email me a quick video of your robot performing a J5 single axis calibration, I would like to get a look at how it behaves and wh...

I ran the exe file on another PC and was able to replicate the issue getting calibration failed. Doing a little research it looks like opening a seria...

When the autocalibration finishes and you get the failed message what position is the robot arm in? After auto calibrating is there a message in the "...

It sounds like there may be a few issues going on here and they may or may not be related. Lets start with the calibration. When you autocalibrate and...

The VIN or 5v terminal is correct.

I count 57 on the belt I have on my desk.

The 7th axis is not factored into the robots kinematics. The 7th axis position is however incorporated into the robots move command so when you teach ...

I just talked with my contact at stepper online and production on 5 of the 6 motor is complete. The last motor is waiting on parts from a facility in ...

In the latest AR4 I have wired the E-Stop to the enable circuit but the arm still collapses as you note. I agree it would be best for the motors to re...

Are you using the DM542 drivers? The high pitch noise is usually a result of having the AABB motor wires incorrect but it could be a driver issue. I h...

its hard to say but I suspect it may be a couple different issues with the limit switches. The J3 looks to be off by a few degrees and I assume its at...
