Re: Upgrading melzi board to a duet board, help please - 9 years ago

Quotedc42 The built in regulator on the Duet is reliable. The reason RRP used the external regulator on some of their kits is that the on board one on the version 0.6 board generates too much EMI for the completed kit to achieve CE certification. thanks for the correction - remembered that part wrong..

Re: Two stepper z-axis - 9 years ago

i doubt it is technically possible for them since this would also mean they could "miss a step" if used alone which would possibly mess up the whole print, no matter which of the motors it is. i was more afraid that the connection between the motor and the threaded rod may slip, but not anymore because i observed them a long time and rhey stayed always in snync (to make this easier for me i attac

Re: Duet 0.8.5 with 2 Z-Axis Steppers - 9 years ago

dont trust me here entirely, but if i recall the documentaion i read regarding correctly this they are simply connected in parallel - so you could alternatively disassamble the plugs of both and put both cables into the same plug (same color wires to same pin, it should be possible to double them) or create an adapter which doubles the pins available (called Y Cable) wait for confirmation of oth

I would say you should check your cables, especially the one of the motor which doesn't work - I would bet there is an interruption somewhere

Re: Temperature problem of heater - 9 years ago

These temperatures are at the lower end of what this thermistor setup can measure - it may sometimes think the cable is broken because the resistance is too high - and heating when the thermistor cable is broken is a bad idea

Re: Upgrading melzi board to a duet board, help please - 9 years ago

from my understanding the Duet Board has an internal 5V Converter, but that one is not entirely reliable hence the external Converter. Also it can draw the 5V from USB alternatively - not sure how much it may draw, but to be on the safe side either connect it to a USB 3.0 Port* or plug a powered USB Hub in between * they increased the possible current there compared to USB 2.0, and altough USB

Re: Strange ripple on only x axis - 9 years ago

what does your Printer look like? and what is the Distance between the Ripples? is it possibly the same as the spacing of the thooths in the Belt?
