Ok, I see.

Backlash is really small, this I can tell you, measuring it, I wouldn't know how to start

These last suggestions I am a little lost on. What exactly do you wante to measure?

My machine is made of servo with planetary reducer (gearbox) in front . Only my z axis is directly placed on ballscrew. This one I remounted once, there are no loose screws there. On the motors also every screw is supertight.

So I am a little lost here guys.

Hi Roger,


Thanks for your input. What is it that you want to measure? The rigidity of the machine?

The whole machine weighs about 3000 kg. The bridge itself is about 1200kg. This is about as heavy duty as a flatbed router can be to be honest. U could mill some steel with this if u wanted too. So there is no actual flex when I put pressure on spindle or table. The dial says 0.

Regards

Stephane

Hi Tweaky

Here you will find the G-code (in txt-file, this forum doesn't allow me to post it in .zip)

Greetings

I tested it and yes I have put if off. But still not a smooth curve

I have tried all of the things mentioned and I got it to jerk a little less. By upping in config -> backlash the speed from 20 to 100% (everything else is on O and backlash enabled is not vinked. Also changed CV for angles to 90 it was on 6 before, all other CV options are off.  But the hesitation is still there in arcs. ( For example milling letters in baroque lettertypes)

What else could be helping out so my machine makes 1 smooth motion and doesn't slow and speeds up at every line of g3 and G2.

Hope you guys have some other suggestions.

Also the backlash compensation mentioned above... Where do I find these settings? Cause haven't found any backlash compensation settings anywhere. 2nd thing. When I activate CV feedrate and set to 100 it makes it jerk more.


Thx

Hi,

I will be looking at what you guys told me tomorrow morning. I wasn't able to boot up the machine today. To busy, I really hope one of these answers will solve this problem for me. Thanks already, I will update tomorrow

Hi Craig,

Where would I find this? This is a setting I don't know where to find.
