problems while probing

jay_s_uk

yes, the timings need setting for them.
Which external drivers are you using?

peterartechno

I am using ES-D808 external stepper drivers with Nema32 stepper drivers ( a closed-loop system).

The weird thing is that the left axis is not working, but the right one has no problems. This made me think that that was not the problem, the timing

For reliable response, pulse width should be longer than 2.5μs.
, DIR signal should be ahead of PUL signal by 5μs

@peterartechno said in problems while probing:

ES-D808

yea, as @Veti says
you'll definitely need timings on those. you may think they are fine but then you'll have movement issues just like you're seeing.
I also use similar external drivers and definitely need timing to get consistent results.
You'll need M569 T2.5:2.5:5:5 on each driver thats external

peterartechno

Thanks! Do I need to change the M569 T2.5:2.5:5:5 to something like T2.6:2.6:65:5?

Where in the config.g file do I put this?

Veti

@peterartechno
append T2.5:2.5:5:5 to the existing M569 entries

try with that for now

jay_s_uk

@peterartechno try out with the M569 timings I gave you above. that should be ok. Worst case you could add half a microsecond but I dont think it would be needed.
I would guess that your current M569 commands looks something like

M569 P0 S0

change to

M569 P0 S0 T2.5:2.5:5:5

You only need to do this to the drive numbers that are the external drives

Thanks

I use 2 X-motors, 1 Y-moor and 2 Z-motors, all with external stepper drivers but that particular one is the only one with problems. I am going to try it right now!

Veti

@peterartechno

do add it to all the external drivers. it will save you headache in the long run

@Veti @jay_s_uk

Thank you so much! It worked! Finally worked out the problem I encountered weeks ago!
You have both made my day

kind regards,

Peter
