Which should be correct. I’ve flashed the firmware 3, downloaded it again, to try to weed out any human error from my part. But nothing helped, so I’m puzzeled.
For now I solved by using a terminal issuing
M92 Z400
To again set the Z axis steps per mm to 400 and a M500 to safe the configuration.
But it seems that my previous M8 threaded rod configuration did not get overwritten by the new firmware.
Thank you for awesome machine, I too recent upgraded to the T8 Lead screw on the Mini Rambo Board using the (MPCNC813MRAmbo_GLCD_T8 Firmware) but, I click on 1mm it moves about up about 5-6 mm up, I sent a clear eprom command to the board, one thing I did see is that the Zsteps/mm reset back to 2267.72 when I clear the eprom, if looking at the attached photos, if can see that the Zsteps at 2267.72 even after I reset them to 800.00 as per the instruct on the firmware page, but if when that . I have attach some photos of the print, it looks like the print head moves up very fast. any ideas, I’m sure I mess it up somewhere. any ideas would be awesome. thanks again
last photos is of the printer before the T8 upgrade 450mm (X) X 450mm X (W) 80mm (D)
If it is being stubborn, just flash the newest generic bugfix from the main marlin branch. Then flash it again with my version. I have disabled the eeprom as it is too sticky.
That will change marlin versions and force an eeprom erase.
Flashing the Firmware with the bugfix patch did clear out the eprom and with the Zstep, however the 3D Parts are still coming out the same has in the images listed above, any ideas, I have charge the T8 Rod with another one. Same problem, I make the print head as close as possible to the print bed where the filament just force on the bed, the layer is way higher then is should, any ideas?
There are a few things wrong here. The amount it is wrong by isn’t common, so I have no idea what is going on. manually moving your machine 100mm in each axis what exact numbers do you get, I need to know exactly how far it is off to figure what the heck is going on?
Do not use a gcode file. use either reptier or the LCD to move each axis, mainly the Z 100mm and give me that distance it moved to the best accuracy you can.
800 is wrong, I don’t think you flashed my firmware. That screen would not match any of mine. Your z should be 400.
You really need to figure out what firmware you have flashed as the mini-rambo driver current is set in my firmware, if you do not have the right one they default to extremely high. The numbers you show do not match any of my current firmware.
Don’t worry about taking over the thread. Problem seems similar enough, its nice to have all the clues in one place. Hopefully I will be able to clear the eeprom tonight. Will let you know if this works or if I need to flash the bugfix.
