Wades extruder and M8 bolt heads... - 13 years ago
Hi to all, Does anyone know the if the dimensions of an M8 nut are different to the dimenions of an M8 bolt head? i have printed off a wades big gear from the prusa iteration 2 files and i tried to fit a M8 nut into the centre hole after it printed. The hole was too small. I have cleaned up the plastic and it still wont fit. The dimensions of the nut are 12.86mm flat to flat, 14.75mm point toby RepRapRaj83 - General
Re: Printer host and slicing software compatibility - 13 years ago
Hi everyone, Quick update on changing the Slic3r. Things did not go as expected. After running the Slic3r program on a pulley stl file, i opened up the gcode file, placed a F60 command in front of all Z axis movements and upoaded it to pronterface. the first layer prints ok but when moving up to the next level, the z axis attempts to move but then whines very loudly and stops. On the Pronterfaby RepRapRaj83 - General
Re: Printer host and slicing software compatibility - 13 years ago
Hi Nudel, I will have a look around for some details on putting together a circuit board for temperature control. I'm already running the extruder motor off a stepper circuit so if a temperature circuit is made, does this mean the extruder controller board will no longer be needed? That said, I will give teacup a try and see how that works. Thanks, Rajby RepRapRaj83 - General
Re: Printer host and slicing software compatibility - 13 years ago
@Sublime - That was my plan providing I could put the command on the same line. @Liberation - thanks for confirming this. I will look further into getting this set up. Rajby RepRapRaj83 - General
Re: Printer host and slicing software compatibility - 13 years ago
Hi Bob, Thanks for the offer. I'd like that very much. Does this require a certain level of programming knowledge to run/install? My skills are very limited so let me know. Hi Pointedstick, Can gen3 handle Marlin? Let me know as i would like to upgrade the firmware. I can get good print quality from FiveD, SF41 and Repsnapper (I know - oooooooooooooooold ) but if I can get Marlin up and runninby RepRapRaj83 - General
Re: Printer host and slicing software compatibility - 13 years ago
Hi, hope all are well. I have been troibleshooting these issues and discovered the following. The heater issue was caused by a loose power lead to my gen 3 extruder board. this was overlooked for a while as the power light remained on during printing due to the movement along the X,Y and Z axis. Tightened them up and all is good. The Z axis movement was due to Gcode. during printing the Z axisby RepRapRaj83 - General
Printer host and slicing software compatibility - 13 years ago
Hi to all on the forum, does anyone out there know if there are any incompatible combinations of host software and slicing software? I'm in the process of changing over slicing from SF41 to Slic3r and I'm having trouble when printing generated gcode through Repsnapper. I know Pronterface/printrun is recommended but I'm trying to focus on one change at a time for the sake of troubleshooting. Iby RepRapRaj83 - General

Hi Sound, Firmware is FiveD and electronics are gen3. I'm not sure if either of the firmwares you mentioned can run on the electronics I have. Thanks Rajby RepRapRaj83 - Slic3r
Re: Slic3r GCODE - No Z axis movement and temperature problems. - 13 years ago
Hi Sound, is slic3r gcode not compatible with repsnapper? I am planning to move to pronterface but wanted to phase the changeover just so I would know the cause of any problems. Thanks, Rajby RepRapRaj83 - Slic3r

Hi to all on the forum, I'm looking to upgrade my gcode generator from SF41 to Slic3r 6 but have been having problems with the code generated by Slic3r. When uploading the file produced by Slic3r into Repsnapper the temperature remains consistent at 195C however after a few minutes of printing, the heat no longer remains on and extrusion stops - .

Re: Cheap and cheerful Bed Temperature control - 13 years ago
Hi Andy, Thanks for the info, 16 amps is a monstrous amount of power. I'm drawing 9.5 at the most. I rigged together the astable timer maplin and its working great with a 3sec on 3sec off cycle . That said, i'm having trouble with yet another upgrade - this time it's slic3r giving me the runaround. If it ain't one thing it's smething else! Thanks again for your help.

Re: Cheap and cheerful Bed Temperature control - 13 years ago
Hi Normsthename, Nice . This is a great way to control the heated bed temperature. I'm trying to get a heated bed up and running using Gen 3 electronics and this looks like just the kind of thing to power/control it. I looked into using a thermal switch but the switch off/on temperatures range is quite high (70C open, 55C close).

dissidence - Hi, yes, the bed is heating the dibond too. With regards to cheap dibond, I got two sheets for about £15 from . The price includes delivery. Much flatter than MDF but since I placed it on my printer, my warping has got very bad hence the need for HBP.

Re: Heated bed hack - currents, voltages and heat output... - 13 years ago
Hi Nophead, Thanks for your reply. I have checked the resistance of the heated bed plate and it is between 1.2 and 1,3 Ohms. With 10v and 8 amps, I could get 80 watts going through the HBP which is a start. I think this can be done through my ATX PSU by using the +5 and -5 wires (http://reprap.org/wiki/PCPowerSupply). I will see if I can get this working and if so report back on what kind of tby RepRapRaj83 - General

I'm in the process of adding a heated bed to my printer and need some input to stop anything going up in a cloud of smoke.

Hi to all on the thread, HereIgoAgain - i'm in a similar position regarding my heated bed. I'm working with Gen3 Electronics and have been testing laptop power supplies with my heated bed since changing my print bed to dibond.

Re: Y Axis Step (Pin 3) and Ground Pin Problems - 14 years ago
Hi all, Probably not the best thing to have attempted but solder wicking around the motherboard ATMega chip seemed to sort the issue. Unfortunately i wasn't able to identify which pins were bridged. That said i'm not even sure if it was due solder bridges of if it was down to a broken connection(s) which was re-connected due to the solder wicking.

Hi all, Further have led me to find similar resistance behaviour when pins 2 and 5 or pins 5 and 6 are connected to the ICSP header on the motherboard (whilst powered off/disconected). When pins 2 and 6 are connected, a constant readout of 0.10 is shown.

Re: Temperature T:0 B:0 on Gen3 Electronics... - 14 years ago
Hi Noobman, I should have explained myself better. The Y Axis motor, ribbon cable and Y axis stepper driver work. I have checked this by testing the same parts by connecting them to both the x and z axis header on the motherboard. When the same parts are tested with inputs from the different axis, all works as expected. I'm having a read of the wiki in order to get a better idea of the electrby RepRapRaj83 - General

Yet more weirdness after going through some of the suggestions outlined. After heating the boards up with a dryer and resoldering connections on the MB/EB, i tried my luck and connected up the boards. Partial success. The temperature reading was being returned and changed in line with when the heater was turned on and off. Then came a check on the Y axis.

Hi brnrd, thanks for your information. I'll dig around for a 'how to' on Q1 and post it. For Q2 - I should have made myself clearer.

Noobman/Nophead, Thank you both for your responses. I'll look at re-soldering the joints on the MB and adding additional ground connections. @Nophead - Could you explain what you mean by trying a pull up on line A and a pull down on line B.

Re: Temperature T:0 B:0 on Gen3 Electronics... - 14 years ago
Hi all, Further checks have confirmed it's a hardware problem - the problem (and solution) remains a mystery. @Noobman - I first looked at the Intercom.h files on both boards – both had matching settings for communicating over the RS485 connection. @Noobman – Checking for the R180 resistor on the motherboard (labelled R16 on the board itself), this is present.
