Hi guys!
For this topic, I have two problems with my 3d printer.
1) My Z axis speed is very slow. I have a system with two Z axis motors and it happend sometimes that I want to level the X axis by rising it all the way up. My lead screws are 8mm/revolution. To see how slow my Z axis is moving check this video at minute 1:20 [www.youtube.com] (this is not my printer) . Can you tell me please what should I set in my Marlin firmware to have a speed of movement like in this video? [www.youtube.com]. When my Z axis is homing, I have the same slow speed.
2) Second problem is refering to heating my hotend. When I connect my printer with Repetier host and I hit the Print button my printer behaves normally. Hotend is heating up without any problem and the print starts having no problem. Though, when I hit Print from SD card on my LCD my hotend starts to heat up and when it's around 210 degree(from 215) my LCD shows Printer Halted, please reset the printer.
This problem i have it only if I'm trying to print from SD card. I have a power supply of 25A at 12V with good wiring connection and the cartrige is 25W. Trough Repetier it takes 2 minutes and 20 seconds for the hotend to reach 215 degree celsius and start to print. And the temp is increasing every second like 40, 43, 45, 49, 54, 58, 62 and so on. Same increase in temperature I have it when I hit print from SD but around 210, 214 LCD shows Printer Halted.
