Here is a image of what I'm askingby phongshader - Firmware - Marlin
I have a question on where the Z_STEPPER_ALIGN_KNOWN_STEPPER_POSITIONS should be measured from/to. I have a bed that is 535x535 with a printable area of 490x465. Z1 is -95,0 Z2 is 565,0 (+75 on x) and Z3 is 230, 645(+180 on y). I think the probe points should within printable area and all on the same radius from the center of the circle created by the z axes...right?by phongshader - Firmware - Marlin
Maybe you can help me out. I just upgraded my printer to 3 belt driven z axes. I did the initial bed leveling by hand to get it close then ran a G34 command to finish the leveling. The leveling was worse after 5 iterations. Tried again and it got worse still. I leveled it by hand again to where the bed was within .01 of tolerances ran g34 again and same thing got worse with every iteration. the dby phongshader - General

No that's not what I mean, the speed multiplier listed in the marlin menu under tuning on the lcd when a print is running. It is not at 100%, I've seen it at 150% up to 300% but it's never the same even when I just re run the same gcode. This happens regardless of the slicer, both s3d and cura files have the same result. I have to turn the multiplier down to 100% to get what the slicer intended.by phongshader - General
I'm probably missing something in the settings...I generate gcode in cura with a 60mms print speed, print with octoprint to an ender3...when the print starts there is a print speed multiplier applied....where did the multiplier come from? I did not add the multiplier. If I load the gcode again it has a multiplier added but it is different form the 1st multiplier. I don't understand where this mulby phongshader - General
During a filament change, M600, the heater cools down by about 10-15 degrees, which is to be expected, and when the filament is loaded the heater tries to warm up but cannot achieve it's desired target and the printer halts in the middle of a print...however when I reset the printer after the halt it has no problem reaching the desired temp. This would lead me to believe that there is a control iby phongshader - Firmware - Marlin
have you tried the latest bugfix? I downloaded (8/30), compiled and my toolchange zraise issue is no longer presentby phongshader - Firmware - Marlin
I downloaded the latest bugfix today and all my issues have been resolvedby phongshader - Firmware - Marlin
I guess I didn't ask my questions in a clear and concise way. Let's deal with the compilation errors. I've compiled successfully on an earlier version of Marlin bugfix-2.0.x downloaded 7/21. I'm unable to compile on a version downloaded on 8/25. The errors seemed to be centered around the lcd code. I can compile as long as there is no lcd or any other screen that needs a menu. The first of many eby phongshader - Firmware - Marlin
In regards to question 2, how would I go about fixing this error /Users/Marlin/Marlin-bugfix-2.0.x/Marlin/src/MarlinCore.cpp:993: undefined reference to `MarlinUI::show_bootscreen()'by phongshader - Firmware - Marlin
I have a similar issue, the z raises 2mm every time there is a tool change but does not lower 2mm to the correct height after the tool change. The printer is just squirting filament into the air after the first layer. I'm looking for a solution as well.by phongshader - Firmware - Marlin
I have a 2 in one out hot end that was working before I swapped out the Rumba board for a Rumba32 board. The printer prints as expected with no tool change however when going from T0 to T1 the head moves up 2mm, as expected, but then doesn't lower back to the original z pos before starting to print again. I found this issue and the op said this was fixed in the latest bug fix. I'm able to compilby phongshader - Firmware - Marlin
One of the bowden collets has failed on the 2 into 1 hot end. I tried to replace it with an E3D V6 collet but that didn't seem to fit/work. Can you recommend a source for replacement?by phongshader - General
I'm looking for a way to test different settings but I'm not sure what to test for. The tests I've been doing just confuse instead of clarify. If I tested different accelerations I could probably get some useful data? I re-ran LA calibration prints. picked 1.0 printed a cube k0.9-1.1 with k0 between each value not what I was expectingby phongshader - Firmware - Marlin
Can you tell me the relationship between acceleration and linear advance? If I increase acceleration how does that affect LA? I have the same question for Ejerk. I've seen some posts that say LA and s curve acceleration are incompatible. I've tried with scurve enable and disabled and can't see any difference between the two.by phongshader - Firmware - Marlin
I've run many tests between 0-2 and consistently got what i thought was the correct setting of 1.1. If you look at my 1st post the cube I printed was at k1.1 then changed mid print to 0 and the corners sharpened up. With that info I printed a test cube starting at k0 and progressing to k2 and it got worse as the values increased not better. Now my understanding of linear advance is the higher theby phongshader - Firmware - Marlin
Some more testing. I don't know what is up with the Marlin firmware I'm using, according to the docs linear advance should be adjusted between 0-2 for v1.5 and 0-200 for v1. What I've found doing tests with whatever version I have works 0-10. Any value above 10 make no change. Based on this test I would chose line 1 or 2 However after testing on a cube to see what the corners look like I would gby phongshader - Firmware - Marlin
What does linear advance accomplish? I was under the impression that it was supposed to cut down on the blobbing on corners, and stops as well as thin extrusions on starts. I must be truly turned around. I did some testing on just k factor settings and got results that I was not expecting. This went from a k factor of 1.1 to 0, notice how the corners sharpened up?
