No Movement with RRF3.1+

curlypaul

I have to admit i didn't try that

But, yes - I now get movement, so can only guess it's got something to do with the Drive5 - removed one on the Duex

curlypaul

Whilst I'm now getting movement, It's still not as expected/desired...
like why does my U carriage move when I home Y ?

But i'll do a seperate post for that.

Would still like to know if I can get movement with the duex5 in it's current state on this FW somehow ?

@dc42 can you comment on that?

dc42

@curlypaul, you've posted your new config,g file, but please can you post the working RRF2.02 config.g file too so that I can work out your machine configuration.

Veti

@dc42 but what would make all motors stop moving in rrf3 if he has a bad driver on the duex5?

@dc42 config.g from 2.02 below..
The one thing that you may notice is that I have to use M669 K5 to get correct behavior, Not K8

One thing I noticed yesterday (running 3.2beta3) is that setting a negative tool offset for Z seems to permanently disable movement for that axis. You can move the axis in the Dashboard panel, the current position changes, but no actual movement occurs.

For example if I do G10 P0 X0 Y0 Z-0.06 then any Z axis movement is disabled and the board behaves as if the drivers were busted. Maybe a similar problem occurs for U.

It took me a while to realize this was caused by the negative G10 P0 Z-0.06 bit, I was convinced I had somehow managed to kill all four Z drivers on my Duex.

How did CoreXYU work before? What happened to V?

curlypaul

@Phaedrux it's a bit hard to explain/remember properly without being with the printer, but the main issue is U will move towards the homed X when homing Y.
also X,Y,U positions are lost/reset when homing other axis
Seemingly random but repeatable moves after and during homing.
Certainly with 2.03,2.04 and 2.05, the UV motors won't move at all if a movement in XY is commanded, resulting in what at the time I called 'angry noises'
Where as 2.02 set at K5, seems to have the printer work exactly as I'd expect

It might be best to video the difference and let that explain

Phaedrux

I wonder if this is a similar issue as here

@Phaedrux I will give this a try at the weekend
Thank you for posting this

dc42

@curlypaul I think I know what is going on. The newer version of the TMC2660 driver includes code to reset the microstep position to zero before it enables the driver. That isn't going to work if the driver has been removed. I will disable that feature for drivers that have been disabled using M569 R-1.

curlypaul

@dc42 - That's awesome - Thank you (and Tony) for looking into this for me
