Re: Gertbot

I see. But how do I set the jumpers? I've attached the two Gertbots via a ribbon cable. How do I know what the ID for each board is then based on the jumpers? How does one call the board ID in the code? I'm quite confused about this!

Re: Gertbot

Ok so I see the relevant explanation about assigning IDs to the jumpers in the manual. How do I do this in the code though? At the moment I only specify BOARD = 1, 2, 3 etc and CHANNEL = 0, 2 etc. Where do I specify ID and what’s the syntax for this? Thank you!

Re: Gertbot

I have built a system which involves two Gerbots, each connected to two stepper motors. The first Gertbot (with two motors) is directly attached to the PI, with the second Gertbot connected to the first one via a ribbon cable. However the second Gerbot has intermittent issues where I have to change ...

Re: Gertbot

Ok that's understandable thank you for your reply. I was also wondering if it is possible to implement a timer in the code such that it starts when the stepper motor begins to rotate and ends when the rotation(s) finishes and calculates the time interval between this? If so how would I go about impl...

Re: Gertbot

Hello Gert, I am using two bipolar stepper motors connected to the Gertbot and a RPi 3 unit to control peristaltic pumps and I was wondering if it was possible to incorporate half-stepping and/or micro-stepping into the Gertbot code in order to get smoother transitions between steps especially using...
