3.2beta2 inconsistent G32

Duet3 6HC+3HC+SBC
First time it tapped the 1st point, then 2d point twice.
Then twice good.
Last it tapped the 1st point, then 3d point twice.

why are you reassigning pins in the bed.g?

TypQxQ

Using the z switch as emergency stop when not using it as probe. Sits under the toolcarriage.

My toolchange macros are also inconsistent.
Makes moves in wrong order.

What firmware version are you running?
I can't say I have any issues with anything running out of order on my toolchanger

@jay_s_uk
3.2 beta 2 as stated in title.
But I downgraded to 3.1.1 now.

Same/similar problem I had, so I can confirm this behavior. Duet3 + sbc + toolboard 0.6 and toolboard 1.0

I also fixed it by going back to 3.1.1. I did try beta 1, which worked fine. Beta 2 is where things went haywire.

Thanks for your reports. There are known problems with commands sometimes being executed out-of-order when using macros on Duet + SBC. These will be resolved in beta 3.

@dc42

Is there a chance that the bandwidth/processing speed differential between the main board controlling movements and the processor/driver on the toolboard can create a situation where the extrusion is out is time/lagging behind the movements of the head? I have had in the back of my mind that the axis movements, if too high would outpace the tool head pushing plastic.
