Hi,
After a rather long story (on this thread) there is a bug regarding how Arduino UNO is able to run stepper motors.
Under AM 3.7.1 no problem, when upgrading to AM 4.0 and 4.0.1 no way to use STEP or DIR commands and when reverting to 3.7.1 my rig is working again...
Hope it will help,
Francois

Re: AM 4.0.1 : Arduino UNO not running stepper motor
Are you driving it directly or through a driver chip?

Through an EasyDriver chip

VID6606 compatible, yes !
It worked like a charm under AM 3.7.1...

Hi,
There where some problems with the Uno and AM 4.0.0.
Could you try flashing the Uno again with AM 4.0.1?

I think he already did. We'll have to try it in the office this week.

I also have this issue with a MEGA...using a Pololu driver it worked perfectly in 3.7.1. No longer works in 4.0. I can hear the coils lockup but no movement regardless of steps /rev or rpm settings.

There's a bug somewhere, the pins just float when using the VID66-06 implementation. We'll investigate next week.

Hi,
I uploaded the latest AM 4.0.2 release yesterday but there is no improvement on that matter.
Any update to come regarding the stepper motors ?
