I successfully converted my Da Vinci printer to run with Repetier, and with the help of the posters below I now have full control over my head and bed temperatures, but now I have a new problem. Whenever I run a print, the printer’s head goes through the motions but the filament doesn’t stick to the buildplate, but instead just loops back up and gets stuck to the print nozzle, quickly creating a big blob that gets dragged around the bed. (more below)
I’ve tried fiddling with my head temperatures between 200-240 c and my bed temperatures between 80-90c, but nothing really seems to work. I have a glass buildplate and ABS plastic, and the manufacturer recommended putting gluestick on the buildplate before a print, but it doesn’t seem to be working now with or without that.
I don’t have pictures or video of it at this time, but could try to get some on request.
Well how high is a 0.4mm nozzle supposed to be from the plate? I’ve tested it using Repetier’s manual controls, and it appears that the nozzle touches the plate somewhere between 2.5 and 2.4 mm for the z’s home.
I normally run it at a paper thickness for a start and then adjust from there with a few test runs of a skirt till it’s a smooth thin run, too low and it starts blobbing and gets a lumpy skirt.
OK think I may have found my problem. I think the reason things weren’t changing when I altered the height was I wasn’t ACTUALLY changing the height!!
I manually pressed the nozzle to the plate til is could lightly bit a piece of paper. This said it was 3 mm above home, same as the printer is set to start at. to I ran a print without the nozzle heated, shut down the printer on the first layer, booted it up and stuck the paper in. Nozzle didn’t give any resistance, so changing my eeprom settings must not actually be adjusting my height like I thought O.O
Well there’s a days struggle down the drain. So how do I ACTUALLY change the print height?
