QuoteFpex What about this community? Will it still live? It is a great source of ideas. Damn. Th death of the cube was ok, but RRP ... a shock, I would think/hope the community could be become stronger. Upon the RRP site, all the shop links are broken, (no spare parts available) but the best resource on there is the documentation is still available that helps people build the machines from theby orictosh - Ormerod

Hi Ian, Sorry to hear that where made redundant from your support role at RapRepPro. Your emails regarding support issues with my Ormerod 2 during the last year helped me so much get my printer printing. They showed good detail and knowledge. Chris Hills 3DPrint and Stuffby orictosh - Ormerod
Yes, using a 4 wire fan and a 2N7000 mosfet is good way to power a cooling fan so it gives variable speed and cooling when needed and requested by slic3r. The yellow wire is not used in this case. Looking at my diagram, I would say the the PWM signal is on the negetive fan0 connection as it connected to gate pin The +12v pin is connected to red (Postive) of the fan The Brown wire is the PWMby orictosh - Ormerod
2 wire fans don't normaly respond well to PWM signals. There is a diagram attached which I used on a RepRap Huxley to conroll a 2 wire fan via Slic3r commands correctly. Before I put in the extra compondents the cooling fan wouldn't disable on the first layers like it was asked. The diagram came from this post With the duet fan0 pin the PWM signal comes out of the postive pin (very top pinby orictosh - Ormerod
Hi Ian, I can confirm the bug; I'm currently printing an item but it's hard to tell if the fan is responding from the gcode produced by slic3r as there is not many overhangs or quick layers. Sorry if this is bit off topic for this thread; I was using 0.78c when building my printer and upgraded (about 6hrs after it hit github) to 1.04 due to the extruder speed bug, before the upgrade the G32 comby orictosh - Ormerod
Yes It's correct, the way I drew it out on paper and explained here was correct but had soldered the mosfet incorrectly. I swapped the brown with the black (Source) , so that the fan's brown (PWM) wire was on the left (drain) with the mosfet flat side down. The fan doesn't shut off completely (it might do as it's in my slicer settings it's set to disable the fan for the first layer) It makes soby orictosh - Ormerod
Hello, I bought the fan mentioned in this post; the 4 wire one. I'm using a 2N7000 method to control the fan from the PWM signal from the duet fan 0 negetive lead. Currently the fan runs all the time and won't respond to a M106 or M107 command. Wiring is as follows fan's black wire goes to the source on the mosfet fan's red wire goes to the fan 0 positive connection on the duet board fan's browby orictosh - Ormerod
Hello, Have you calibrated your stepper motors so the software knows to step the motor so many steps per mm? There is good guide here Triffid Hunter's Calibration Guide getting the steps value in the firmware correct for each of your axis (x,y,z and e). As looking at the photos and you stating it's off by 7mm, your steps_per_mm values within the firmware could be off on 1 or more axis. It alby orictosh - Reprappers
