Re: Electron 3D - Sixth Generation Prusa i3 Anyone? - 8 years ago
Great summary. Can you share what you did for your extruder? I bought the all metal parts off ebay and they don't fit the mounting. I've tried printing a few things off thingiverse with no luck.by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
I bought one of these metal extruder upgrades for my migbot. It looks like a much better extruder than the printed one it came with. Problem is it doesn't fit inside the metal bracket. There isn't a good way to mount it and the level touches the metal preventing it from being used. I was thinking of replacing the whole x-carriage with something like this for the prusa. Not sure if the spacingby kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
Thanks for the help gwc2795 . It's the sensor that came with the auto-level upgrade. Pulled the sensor wire(black) and the LED stays on. This sensor was working perfectly when I was using the 12V supply. I'll connect the board back up to the 12V and see if it works. If not, I guess I fried it somehow. I have a printrbot metal. The sensor on that one is really nice. If this one is defective Iby kareem613 - Prusa i3 and variants

It never changes. Always on. Or do you mean varying in brightness?by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
I just upgraded mine to a 24V power supply. I did the PID autotune and that looks all setup right. Here's my issue. The Z-Probe is permanently reporting triggered. The light is on no matter how far away it is from the bed. The label on it says it's good for 24V. Any ideas on what might be wrong? Is there something to adjust on the board or the in the firmware?by kareem613 - Prusa i3 and variants
Re: Can't tune Z height "endstop hit: z" - 8 years ago
David J and eried. Thanks for the ideas. They sent me looking in the right direction. The issue was Z_MIN_POS. It was set to 0. Had to set it to -1 to allow it to go lower. I already had min_software_endstops false. I thought that's what would allow it to go below Z_MIN_POS but I guess not. I'm good to go now though!by kareem613 - Prusa i3 and variants
Re: Can't tune Z height "endstop hit: z" - 8 years ago
Quoteeried No I mean: const bool Z_MIN_ENDSTOP_INVERTING = false; Thanks for the idea but that definitely wasn't it! Setting that to true caused it to drive right into the bed during homing. To clarify, my issue isn't that it's not homing. It does. The issue is that I'm unable to tune it to get close enough to the bed for the first layer once it starts printing.by kareem613 - Prusa i3 and variants
Re: Can't tune Z height "endstop hit: z" - 8 years ago
It is false already. I thought that says don't go past the min range defined in the firmware only and that nothing gets it past the hardware endstop. Am I wrong?by kareem613 - Prusa i3 and variants

Can you explain a bit further? I'm familiar with the configuration.h file just not sure what you mean. Thanksby kareem613 - Prusa i3 and variants
Can't tune Z height "endstop hit: z" - 8 years ago
--- <--Probe height --- <-Hotend height (~1mm below probe) When I home (G28), Z is sitting at 0.16. I have a Z offset (using M206) of -0.35. Problem is once I start a print it immediately shows "endstop hit: z". Z = 0.25. Bottom line it won't go any lower than 0.25 and that's not low enough. The probe is installed as high as it can go to get the nozzle as clby kareem613 - Prusa i3 and variants
Re: Electron 3D - Sixth Generation Prusa i3 Anyone? - 8 years ago
What online instructions have you found? All I had is the info on the SD card. Has anybody got their hands on the marlin source for this one? I'm using what was posted for the migbot in another thread. Works fine except for offset. I can't get this puppy to print centered and calibrating Z height is driving me nuts!by kareem613 - Prusa i3 and variants

Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
For anybody in Canada looking for a power supply, here's the one I'm about to order. It matches the specs gwc2795 mentioned above. The pic even looks identical so it may very well be the exact same one.by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
So you're running both supplies? Isn't there a way to use the 24V for everything?by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
Is anybody else having issues with the fan duct? Mine appears to be aimed a bit high and the airflow hitting the nozzle tip. Once the fan kicks on the 2nd layer the nozzle tip drops a lot. Enough to hit the safety threshold where the extruder won't extrude. I tried printing a replacement from here with no luck. What's everybody doing her for a fan duct?by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 8 years ago
That's good info about using a relay to heat the bed. 1. It's the extruder hooked up via relay as well, or did it get stable because the board is dealing with the heat bed anymore? 2. I have a 12V power supply. Think I can get benefits by hooking the bed up via relay even right a 24V supply?by kareem613 - Prusa i3 and variants

QuoteYakuza Hey guys, its been a long while. Just read a ton on here. i think this firmware and settings i have linked here should help and make a difference.

With nothing hooked up to the power supply it's putting out a proper 12.01V. I'm using the config from the first page of this thread. Are the heat bed settings in there correct for the MK2 heat bed?by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 9 years ago
It would be great if there were a diagram showing how all these offsets came together. I'm sure once I understand it it'll all make sense. Just need to get there.by kareem613 - Prusa i3 and variants
Re: Migbot Prusa i3 Unofficial Support Thread - 9 years ago
Here are voltages with the heatbed on and off. Heat bed off 1. PS voltage: 10.8V 2. Board Connector 10.8V 3. Heat bed Connector: 0V Heat bed on 1. PS voltage: 8.89V 2. Board Connector 8.89V 3. Heat bed Connector: 7.54V I'm guessing this means I have a shoddy power supply. Is that right? QuotegatorNic I think you should check your voltages. Hotend should easily and quickly go well beyond tby kareem613 - Prusa i3 and variants

Re: Migbot Prusa i3 Unofficial Support Thread - 9 years ago
I'm working through this offset. Thanks for all the awesome info! My offsets should be X 15 Y -35 I had to set this so I could send the y-axis into negative territory. Should this stay false now that I know the numbers? min_software_endstops false Here's the manual home sections. Can I get a sanity check because this doesn't seem to be working yet?

Re: Migbot Prusa i3 Unofficial Support Thread - 9 years ago
Are the manual home positions correct? I have a new machine. Prints fine, but not centered and so my build volume is reduced. I've been trying to get it right all day. I tried your values for all the mechanical settings and I can't get it right. First, is this a good way to test if the values are correct? Using the LCD panel 1. Auto Home 2.

Re: Migbot Prusa i3 Unofficial Support Thread - 9 years ago
I can't get the hotend to heat up past around 165. When I remove the fan duct it gets up to the 185 I asked it to. It appears the fan duct is actually aiming at the hotend instead of below it. There doesn't seem to be a way to adjust it. Had anybody else encountered this?by kareem613 - Prusa i3 and variants
