Interestingly I have done the probe test. During a test print, watch the first layer go down and adjust the Z position using the baby stepping function. If the probe needs to be deployed before use (e. No trigger on probe after full movement meaning. g. BLTouch), test the deploy and retract functions, by sending M401 to deploy the probe and M402 to retract it. Before starting this test, first calibrate the probe X, Y, and Z. offsets as described at the beginning of this document.
Some probes can have a systemic bias that corrupts the results of the probe at certain toolhead locations. Here, similarily, the probe is triggered (seen by endstop watcher), well before move ends - but never acted upon by stopping the steppers. Nozzle_y_position - probe_y_position. It is also a good idea to reduce motor currents in case of a crash. The most aggravating thing is that, if I add a debugging line to the beginning of. If you find any, delete those lines and save the file. Differ by one Z "step distance" or up to 5 microns (. Note that if a change is made to the printer's motion system, hotend position, or probe location then it will invalidate the results of PROBE_CALIBRATE. RESTART command so that. I've verified the issue isn't an issue with the probe (oscilloscope shows triggering pulse when the nozzle touches the bed, when this failure does occur). Probe triggered prior to movement. This one's really got me beat... It's almost as if the interrupt isn't triggering, or something's going wrong during the interrupt call.
Tape/marks from the bed, and then issue a. Interestingly I did have an issue recently where modifying my babysteps/z-offset downwards by the minimum amount during printingt would sometimes cause the z axis to move down excessively (i. e. I'd make the minimum step, and the nozzle would dive into the bed). Static test of the Z probe. I have a little more logging of this issue captured since. Navigate to the other XY positions, repeat these. If the results of the test show a range value that is greater than 25. microns (. Ideally, the command will report. For delta printers, try measuring the z_offset at a position near the A tower, at a position near the B tower, and at a position near the C tower. No trigger on probe after full movement in photoshop. Hey @shitcreek, Also, I'm aware this says to disable in case of failures - but this issue isn't caused by the probe going into error state or the probe failing to trigger (since Marlin seems to see the probe getting triggered in the logs, it's just seemingly not acting upon it? The new values take effect.
Calibrate the z_offset again. Connect to the printer from a browser or via USB. If you have access to the CAD files for your probe mount you may already know the probe X Y offset, or it may have been provided to you with the parts. PROBE_ACCURACY command allows one to run tests with. PROBE_CALIBRATE command to start the tool. For any other type of Z probe where the probe triggers before the nozzle contacts the bed, it will be positive. The firmware needs to know the position of the probe in relation to the tool. Hi all, Quick note: with a successful probe, we see "Completed quick stop" called after endstop interrupt triggers this action in. That is, ideally the probe obtains an identical result on all ten.
One can check for a location bias by using the. However, it's normal for the minimum and maximum values to. Used instead - see the Bed Level document for further. If the nozzle does not move to a position above the. Those steps are complete one can. PROBE_CALIBRATE command, TESTZ commands, and. I got the probe to save me time levelling the bed, yet I've ended up not printing anything in a little over 2 weeks as this has been bugging me so much! Note ***that the offsets will follow the right hand coordinate system, meaning that X movement to the left of the nozzle will be negative, and right of the nozzle will be positive. 506948 Recv: // probe accuracy results: maximum 2. If the difference between the minimum reported z_offset and the maximum reported z_offset is greater than 25 microns (. Used to obtain this value - it will run an automatic probe to measure. In most cases, the nozzle tip. Navigate to the OctoPrint "Terminal" tab and issue a PROBE command: PROBE.
G-Codes document for further details. Samples on each probe - read the description of the probe. If your probe uses the nozzle tip, the X Y offset would be G31 X0 Y0. ACCEPT command, but. ABORT the manual probe tool and perform.
