Re: amperage to hotend
Depends on voltage and resistance. Divide voltage by hot end resistance to get the current. Most heaters are 30-40 watts which at 12 volts, equals 2.5-3.33 amps.

Measure the resistance of your heat bed in ohms and divide it into 12 (assuming you are using 12 volts). The quotient will be the amperage that the bed will draw. EDIT: I misread - I thought you said...

View ArticleRe: Microstepping driver A4988. Help
A more realistic maximum for the A4988 stepper drivers is 1.2A. They will deliver the current you set them to, as long as they don't get too hot. So you can use them with your stepper motors, but you...

Instead of removing the "lock" of the ribbon cables, one can probably also just pull the plastic part of the socket from the adapter PCB turn it 180 deg and push it back on. This way, there is no...
