Pause when traversing to avoid gantry shake

[brendic (Bren)]

Hi,

Is there a way I can slow down the head acceleration enough to limit gantry movement when etching lines close to each other?

Or even a way to make the lines etch linearly similar to the fill.

I’m etching cartoon hair and there’s so much shake when the head zips up and down and diagonally to each strand.
I probably need about 0.5 of a second for the gantry to not move.

Thanks

You need to sort out which movement is causing the issue you want to resolve.

1. is it just general high speed? If so, reduce your cut layer speed
2. is it actually just overall acceleration irrespective of speed. You can change this in your smoothieware configuration for “acceleration”. Apparently this can be changed on the fly by issuing M204 S#### where #### is acceleration in mm/s/s.
3. if it’s caused by the rapid speeds between parts you would need change your max travel speeds in smoothieware configuration

Thanks.
I slowed the speed of the line and the power way way down.
It seemed to have helped.
It’s a shame smoothieware can’t be updated quickly. I used cohesion3d and I have to remove the SD card, update and insert for each change.

I haven’t had to deal with that but sounds like a pain. Some of the changes you should be able to modify on-the-fly in order to test. And then make permanent in the config file.
