HI there.

Could someone please have a look at my setup here.
I am getting the dreaded joint following errors (My weed dealer is lost again) when jogging the x axis but not when jogging the others.
As far as I can see the x & y should be setup the same (except for the table size)

Can any one see why it should happen on the X but not on the Y or Z.
I should also mention that I am using Remora-rt1052 on an EC500. 

Thanks

 

Possible to post your full config directory? 

Hi Scott 

I have deleted the qtvcp folder otherwise its too big (2.5Mb limit. Really?!?)

I have found that turning up the pgain on join 0 (X axis) to 100 enbled it to work up to the full 4.5 m/min.
I'm still not sure why the X is different to the other axis.

With the scale =550 & the max speed set to 4500 mm/min it seems I'm getting to the limit of the max steps that this box can put out (with this firmware)
Does that seem right according to you calculations.

Thanks for any insight 
Alex

 

Are you using steppers with no feedback?

Iv gotten my homing switches as limit switches and works ok. But the lathe also has a prox sensor which would be much more accurate. I have added the following lines to the ini and Hal. It finds the limit switch and then goes looking for the prox. The prox triggers and it also triggers in hal but it dosnt trigger as home and keeps searching till it bottoms out. Any ideas? I'm on Linux 2.10
The prox by the way is a pulse from the encoder, triggers every full turn of the stepper. Pulse is on input.07

Not sure, but this thread might help.

Thanks for the link Scott,got it working. Thats the homing/limits, axis and spindle working. On to the tool turret now. also is there an encoder in remora fast enough for a spindle ?
