When I measure from D8, nothing happens. If I connect the bed directly to the PSU, the bed is able to heat up. When I pulled the wires out of the green terminal on the RAMPS, I noticed the ends of the wires were blackened. Only the wires from the 11A side were blackened - the wires from the 5A side were fine.by Axis - Reprappers
QuoteMy heatbed has been working well enough for the past month, until today when I tried to set the bed temp higher than 110C. I set the bed temp to 120C, but it seems that the highest it will reach is 113C. So I tried to print at 113C. After several minutes of printing, the bed temp started falling. I tried to reset the temp to 110C, but it didn't work. I restarted Pronterface and restarted theby Axis - Reprappers

Hi, I'm trying to print the calibration object called 'precision-block' with ABS. I don't have a problem getting the ABS to stick to the Kapton, but the overhangs curl up. I tried using cooling fans, but that made it worse by warping the object off the bed. Anyone? Thanks.by Axis - Printing
Okay. After doing the calibration, my E_steps_per_unit is now 583 and it works fine manually at 30mm/min. But when I tried a print, the filament jammed. In Slic3r I decreased the parameters under 'Print speed' to 15, 15, 30, 30, and 30 (half the default), but it still jammed. I decreased the print speed again to 10, 10, 20, 20, and 20, and now it seems to print okay. Is it typical for a printeby Axis - Printing
I just realised the filament isn't getting pushed through consistently. The extruding motor works fine, but every couple of seconds the filament will stop-and-go, grinding on the hobbed bolt. I tried tightening the idler block, but the filament would fold or curl up inside the block. It seems the plastic isn't melting fast enough. I tried increasing the temp to 240, but no difference.

Oh I get it. Fuck, sorry, I'm bad at math. 1+1=2, right? Thanks, all.by Axis - Printing
If I tell it to extrude 100mm and the mark is 30mm from the extruder, wouldn't that mean it fed 70mm? Shouldn't it be 100/70?by Axis - Printing
@nophead: If I mark it at 120mm, how come I'm telling it to feed 100mm instead of 120mm?by Axis - Printing
I dunno what gauge the ribbon wires were. There's no numbers printed on it, and the website that sold them didn't say. But I bought some 18 gauge wire, and it seems to work okay now. Thanks.by Axis - Reprappers
Thanks for the reply, Dale. In 'Configuration.h', I picked one of the defaults: // X, Y, Z, E steps per unit - Metric Prusa Mendel with Wade extruder: float axis_steps_per_unit[] = {80, 80, 3200/1.25,700}; I was thinking of increasing the E steps-per-unit, but was scared I might break something. But now that you mention it, 700 is probably meant for 3mm filament? Digging around the forum, I sby Axis - Printing
Hi, I'm new to electronics. I have a Prusa Mendel kit that came with a PC power supply, a PCB Heatbed MK2, a thermistor, an MDF plate, and ribbon wires. Sandwiched together, from bottom to top, I put the MDF, a piece of cardboard, the thermistor, the PCB, and then a piece of glass. I attached 2 yellow and 2 black wires from the PSU to the 11A part of the RAMPS terminal, peeled wires from the rby Axis - Reprappers
Nevermind. In Slic3R, I turned the printing speeds down to 10, 10, 20, 20, and 20. And now it's starting to look more like a cube.by Axis - Printing
Hi, I'm new to calibrating 3D printers. I have a self-assembled Prusa Mendel with Wade's extruder, 1.75mm filament, .3mm nozzle, and Slic3r settings set accordingly (with layer height at .175mm). Printing a test file '20mm-box.stl', the first layer seems to print okay. But after that, there doesn't seem to be enough plastic coming out. Anybody know what I might be doing wrong? Thanks.by Axis - Printing
For the first 10 seconds, the printer moves fine - after that, the motors will randomly make partial movements and clicking sounds. I'll try to adjust the stepper driver current. Thanks Dale.by Axis - Printing
