Re: speed, acc, dece and position command issue

1. I would be suspicious of poorly tuned PID settings. Accel and Decel values can hide problems with PID settings.

2. Can you provide a video of the system running. Im not sure I understand exactly what it is doing based on your graph. You can send the video to support@basicmicro.com

Re: Need help troubleshooting a burned MCP236.

yes, agreed on the factor 10 problem. That is just way to convenient to not be some scope setting. Let me know. I currently get in at 8am PST and leave around 7pm PST. I can push the leave part a little. Prefer not to try making it in early than 8am though.

Re: Sudden Initial Motor Movement with Position Control

Make sure you are using Basicmicro Motion Studio and have the latest firmware installed 4.1.34. That problem was fixed a long time ago, so if you have it, it means you have old firmware or it isnt that problem. That problem was fixed by updating the position internal variable whenever switching from...

Re: HM1 Home Switch triggered by motor overcurrent?

The internal pull-up/downs are weak. You may need to add external ones, up or down dependin gon your settings. When I say weak I mean weaaaaaaak. :) If oyu are using that heavy of a battery I expect the motors are not tiny either. The bigger the motors the more likely you will have problems with the...

Re: Arduino control AND RC?

S1 and S2 inputs can only be Packet serial OR RC mode, not both at once. If you are using an Arm based Arduino you may be able to setup a USB host and talk to the Roboclaw with USB packet serial which would leave S1 and S2 free for RC control. Otherwise, the answer to your question is no.

Re: Sudden Initial Motor Movement with Position Control

My suspicion is the roboclaw thinks it is somewhere other than where you think it is when you first start your program. You should always check the current position or home the motor before making your initial movement.

Re: Using 3 roboclaw, packet serial, USB

Yes a common ground is required between all roboclaws when you are using multiple units like that. The USB only supplies a ground between the PC and the first Roboclaw.

Re: HM1 Home Switch triggered by motor overcurrent?

Based on your description I would start with a stronger pullup. You can go to 1k safely enough. However your power levels are low in general. 7amps is nothing. I suspect something else is going on. Put the scope on 5v and see what happens there. The internal pulldown(I assume you have inverted the p...

Re: Motion Studio - Auto-Tune PID crashes app

Each autotuner function measures QPPS and then runs the autotune function. You no longer need to enter tha QPPS values before starting. It will be overwritten. The Position Autotuner also run s a velocity autotune if you have it set to PIV which will overwrite your velocity tuned settings if you had...
