Ahh - nice one! I had no idea this section existed.

Will be sure to post when if I find the time!

It seems my penchant for hobbies that require a steep learning curve remains strong. haha.

@Phaedrux said in G-Code to slow down printing at corners of objects.:

I think you're describing jerk.

OK so I have slowed instantaneous speed down to 12 mm/min from 100 mm/min in the config but don't seem to be getting any real change when running the print.
Is there an override somewhere I might be missing?

Ahhh of course! Thanks mate - I didn't even think to edit in the config.

I'll try it out and see how it goes.

Hi guys,

Weird one that I am hoping some experts can weigh in on.

Long story short - I am testing some composite materials that are proving difficult when the nozzle changes direction (think a square cube, each layer, at the corners, it is pulling the composite towards the centre).

I think I can get some success if the print was to slow down at the corners, is there any way I can change the G-Code (rather than editing each line manually) to slow down when approaching corner moves?

Hope that makes sense!
Thanks,
Callum

Hi guys,

I have had a read of a few posts regarding this but have been unable to determine the best solution (even if just for now).

Having some troubles with the M999 command when sent from the Paneldue on a Duet 3 6HC + EB 3HC.

It works as intended for all components connected to the MB but one of my Y-Axis' is connected to the EB and continues on moving, which is causing issues (balls screw on each Y connected to a N23 with enough torque to send the axis off track)

Am I best putting a momentary switch in that can send a command to reset both?

Ahh - nice one! I had no idea this section existed.

@Phaedrux

She's a big one, that's for sure.

Two Bondtech QRs' a huge ATP5 bed and some serious current should hopefully see large scale prototypes be turned around quickly!

@Phaedrux

P.S. How do I mark this as solved?

Or is that something you guys do?

@Phaedrux

Yep - I will do that now. Cheers.
