I believe I have now solved my problem. I actually had a number of items which needed fixing. For one, some of the screws holding my Z-axis lead screw in place were loose, so my z-axis was no longer aligned properly. Since I have two lead screws, this meant that the carriage was no longer horizontal, and it took more torque than usual to move the carriage. In fact, I was fooled into thinkingby Dr. Dave - Firmware - Marlin
I have also noticed that there does not seem to be a way to compute the PID values for the bed from the LCD. At least, I have not yet found lines in the Configuration files which control this. However, I believe that you need to set #define PID_PARAMS_PER_HOTEND in the PID section of Configuration.h in order to see PID settings for both E0 and E1.by Dr. Dave - Firmware - Marlin
Quotekc8iqw QuoteAre you 100% certain you gear/teeth/belt ratio is right? Yes. This is a new problem which arose after I updated my Arduino build and the Marlin build. The output isn't slowly creeping across the plate, but it keeps moving right and backward. In fact, when I manually move the X or Y axis, the print head hangs in one direction, but moves OK in the other direction. QuoteMightby Dr. Dave - Firmware - Marlin
I, too, am having similar issues. However, depending upon yet-to-be-determined conditions, the problem has manifested itself in both X & Y directions, as well as in the Z axis. I have not tried to lower the belt tension, but it is probably a good idea. It goes along with my impression that the problem is that the motors cannot handle the sudden movement requested (I use slic3r), and that mby Dr. Dave - Firmware - Marlin
Addendum: After a bit of exploring, it looks like there is at least one, if not two software errors involved. I will try to further define these and then submit them. The scenario: reprap 3D printer (in my case, an Artifex2Duo All Metal) with two extruders which have different PID values What I have found is that when using the M503 command, both extruder PID values are not always printed.by Dr. Dave - Firmware - Marlin
I have an Artifex2 Duo 3D printer, which has two extruders. Because of changes I have made, they are no longer matched and I have now calculated two sets of PID values, one for each extruder. However, I can't figure out how to enter these values into the Marlin firmware, and can't find any examples for how to do this. I'm currently using Marlin 2.1.0.5 with Arduino 1.8.12 and my printer has a RAby Dr. Dave - Firmware - Marlin
Thank you. I did not realize. I don't see how to do this. Perhaps a moderator can delete this thread for me. I will rewrite this thread (I've realized I made a number of errors in how I described the problem) and put it into a more appropriate forum later tonight. Thanksby Dr. Dave - Smoothie
