So I'm fairly confident this is a bug and not just on Marlin 2.0. The new information i have is this: Just flashed the firmware and did a test to see if Y-axis homes correctly and it does. Then did a G0 Y10 command to see if it moves in the correct direction and it does. Tried a G0 Y90 to confirm and it does. Then uncommented manual home positions to 0 for testing. #define MANUAL_X_HOME_POS 0by keen101 - Firmware - Marlin
Quotedustinoff It should be G0 X90 I just reflashed and tested G0 X90 and it works as you said. I must have tried it with a lowercase x. It seems to be case sensitive. I will use G0 instead of G00 here on out. Thanks!by keen101 - Firmware - Marlin
Quotedustinoff The stepper motors will produce a "grinding" sound if they are: Jammed, as in hitting an endstop, bed, etc. trying to run too fast and slipping over the belt cogs. Since you are in the middle of the bed, running fwd or bwd should make no difference. Did you typo or are you actually sending G00 X90 command? It should be G0 X90 I think the key to this would be to determine what isby keen101 - Firmware - Marlin
On the lulzbot mini the hotend probe is directly connected to where the mechanical end stop would normally go. Bad engineering.by keen101 - Firmware - Marlin
A quick update to this. I have tried Marlin 1.1.9.1 and have reproduced the bug. It does not do it on the older originally lulzbot mini marlin source, but it still has bed levelling enabled as i can't disable it without breaking the steppers.cpp file. I'm starting to wonder if it is a bug only present when having bed levelling not enabled. And since no one is using a printer without bed levelliby keen101 - Firmware - Marlin
Thanks for the reply. I think i figured this one out. Yeah I've been messing with it this week. The lulzbot default firmware had a z-offset but that was tied to the automatic bed levelling which I temporarily disabled since I no longer have bed levelling washers. So in essence I am trying to do this on a printer with no bed levelling and therefore no M581 z height offset anymore. As of now Iby keen101 - Firmware - Marlin
I’m currently in the process of upgrading my Lulzbot Mini into having a Prusa Mini bed. Making good progress on it. Decided that with removing the bed leveling washers i needed to flash custom marlin firmware. I grabbed Marlin 2.0 and got nearly everything configured and even got a test print (although it needs some tuning). The problems arose when i tried to follow this guide to center the printby keen101 - Firmware - Marlin
Could someone clarify the difference between Z_MIN_POS and MANUAL_Z_HOME_POS? I am currently modding a Lulzbot mini to have a prusa mini bed. As such i need to write custom marlin firmware for the new bed height not to crash. I am confused at how to use each setting properly.by keen101 - Firmware - Marlin
I was just thinking that we could start a new way of thinking about community. Maybe someone should eventually start a "Migratory Loanable Reprap Box" like The Great Internet Migratory Box Of Electronics Junk. My idea involves having a complete medel kit "on loan". Basically someone (maybe it will eventually be me) donates a Reprap for helping others borrow it to print their own parts for theirby keen101 - General
Yeah, bothacker sharing those breakout files would be cool. If not, i'll just make my own breakout boards.by keen101 - Controllers
