Waaaaaay too slow
-
Hello fellow forum members,
My machine is working fine and well, but I have a minor issue. My homing speed is really, really slow. (my x and y axes are moving at about 0.5 mm/s). Overall, mesh bed probing is taking a little over an hour! Which part of my config file do I need to change to up the speed?
Thank you for your consideration.

@Super_Sonic_7036 Sharing your config.g and homeall.g files will allow us to help you. Also send M115 to the Duet, and post the response.

these are in mm/min not mm/s as maril or other have, could maybe explain your issue?

Your F and T values are used for probing and travelling between points. They are set in mm/min, so you have them set to basically a standstill.
Try F200 and T6000

Thanks, I'll try that now.

Are you sure your Z steps per mm are 4000? That's the default used by the configurator, but chances are it's not right for your setup.
How is your Z axis setup?
M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 X100.00 Y100.00 Z80.00 E1200.00 ; set maximum speeds (mm/min)
M201 X100.00 Y100.00 Z5.00 E250.00 ; set accelerations (mm/s^2)Bearers comment goes for the other speed settings too. Your values are very conservative. You will have to do some testing, but they could all likely be increased by a factor of 10.

My Z-axis has been running fine, but I'll consider changing that if I see too it. Thanks for the concern.
-
And if anyone is wondering, I'm using a Printrbot Simple Pro bare-bones kit, so if you have any suggestions, feel free to tell me.

Update:
My mesh bed probing is moving at a much more desirable speed, thanks!

@Phaedrux
I took your suggestions into account as far as speed goes. I added a zero to the values that I thought could go faster, and my machine is now running at an even better pace. However, I had to reduce the acceleration and speed values of my extruder, as it was moving to fast, and it never properly gripped the filament. I'm still testing things as far as it goes, but so far, things are moving better.
