Chimera Dual Hotends

Post by Dave69 » Tue Jul 16, 2019 5:37 pm

Hi guys need some help.

Got it all set up and some what printing. My problem is this I start the print it lays the first layer then re homes but its trying to go past the endstop with grinding, once it feels it has done what it needs, it goes back on to the printing board quite away from initial layer and starts the print. I have attached a picture so you can see what I mean.

I have been all through Marlin changing and re changing to no avail, inverting does not help just makes the issue even worse.


The only thing I can think of now is something maybe in the G.code.


Is there anyone here that may have or had the same problem and knows what I need to do to correct said issues.


TIA

Hi, from your print model is seems the print layer shift,
you can try 1. Check the belt tightness;
2. Whether the bearing and pulley are issued (lubrication can be lubricated);
3. Reduce printing speed;
4. Adjust the drive board
I hope this can help you.

Hi, you can refer to this: turn the voltage clockwise and decrease the voltage counterclockwise.
