Re: Frustrating extrusion problem - 12 years ago
I've discovered the problem! Jgilmore is right about the GCode file not containing G92 commands, but strangely they are only missing for the first three layers. So the extruder basically goes all the way back to E0 after a layer but without it actually being reset! But then after layer 3, the G92 E0 lines exist for the rest of the print? Why would it only be missing for the first 3 layers?? I'vby robrob - General
Re: Frustrating extrusion problem - 12 years ago
Using Gen 6 electronics with the latest firmware, just using reprap host software to convert the STL. To be honest it hadn't occurred to me that it might be the GCode causing the problem, perhaps I should use repsnapper next time (and is repsnapper better)? The GCode is below showing from layer 1 to layer 2 (minus the repetitive bit in the middle) ; GCode generated by RepRap Java Host Software Gby robrob - General
Frustrating extrusion problem - 12 years ago
The first layer is put down fine, but before the second layer every time, the extruder winds itself backwards for at least 6 or 7 seconds until the filament is almost completely out! Then when the second layer starts obviously there is no filament to print with. I can't find the setting which deals with this in the host software of firmware? Has anyone had this problem and how do you reduce the bby robrob - General
Re: Gen 6 power problem - 12 years ago
Thanks again. It's a heater block by the way. I'm a bit of an electronics novice so.. presumably the board has to be plugged in and running to test all the bits you suggested using a voltmeter?by robrob - General
Re: Gen 6 power problem - 12 years ago
Thanks for the advice JB. When I plugged them in separately it was only the heater that makes it flash! So problem found, now how to solve it? I'm wondering if it could be something to do with the wiring (although it all looks fine), or whether it is definitely something to do with the board (which leaves me pretty starnded). Any ideas?by robrob - General
Gen 6 power problem - 12 years ago
Everything been working fine, but when I just tried to power up the reprap, the power LED and debug LED just keep flashing. The power supply light is flashing too which is strange, so is this a power problem or a board problem? When I plug the power supply in on its own, the light stays on all the time so bit worried the board is fried.. If it is the board, anyone know what happened and/or why?by robrob - General
Re: Everything is scaled up!? and other issues.. - 12 years ago
No modifications.. I'll try reinstalling the firmware and see if that works. I found this on the wiki, maybe I'll try this too: 'A good way to set this is to get the machine to build a long thin brick 100 mm long and a few mm deep and high. Then measure the object with accurate vernier calipers (giving length L, say) and change this value accordingly: XAxisScalenew = XAxisScaleold.L/100. 'by robrob - General
Everything is scaled up!? and other issues.. - 12 years ago
My reprap is printing but everything is scaled up. So it thinks the dump point is at 80mm not 130mm, and a 30mm cube printed at 45mm? I think this is probably to do with the step rate but I'm not sure which setting to change. I'm using Gen 6 electronics. The X and YAxisScale(steps/mm) are both @ 7.99735, and the ZAxisScale(steps/mm) @ 320. Also, when I change an stl file to GCode, it doesn't stby robrob - General
