So I could not find a bug report forum so I might as well write everything in one post instead.
So I decided to start up an prototype printer we built at work a while back but had stood unused for about 1.5-2 years and set it up for use and calibrate it.
The upgrade first failed when I tried to install the latest immediately but worked when I did the step by step upgrade as the instructions said so that was my mistake and in the end no problem.
- The max and min for the print volume had been reversed.
- One of the motors directions had been reversed.
(Those two added together to a rather unexpected behavior with the axis being driven to the defined max and min without stopping between everytime a move instruction was given. see video).
- After I got everything working and setup the web interface suddenly complained that it couldn't save a file I was editing and when I tried to open it again it was empty so was every other file.
When I shut down the printer and checked the card it was suddenly not readable and windows wanted to format it again.
Some other stuff:
What is the proper way to define the offset of the Probe in relation to the nozzle?
I have defined the print volume as the area that the nozzle can reach so that 0:0:0 is when the x and y endstop is triggered and the nozzle is in hight with the print bed. (furthest back and to the right).
My assumption was that if the probe offset was correctly set it would still move the print head with the previous defined limits and just do a software correction to the heightmap etc so that the height would be correct with regards to the tool position not the probe.
When I set the offset between the tool and the z-probe with G31 and run G29(and G32) the printer tries to move the probe to the right to reach 0:0 ignoring the triggered endstop and making a whole lot of noise as it was running full speed into the x- stepper.
Is this a bug or expected behavior and what is the way that corrections to probe offset should be used with the heightmap.
I think that it is a good idea and helpful with it giving information on how many turns to rotate the screws I am unsure how correct the values can be calculated without the offset set.
I would also like to be able to have it write out the z trigger heights as it did in previous versions so I can check if the values are looks to be correct.
G32 interactions with G29.
The company I work for use a removable build plate with 4 calibration points. We would of course like to use the heightmap to get the best possible result but we would like to be able to use the G32 measurement before print to do a quick check before print and to do some fine adjustments of the base plane the heightmap is applied on.
It would also be a good thing to be able to use the G32 for a confirmation that the build plate is within limits for what is considered flat and can be corrected for in print. If the build plate fails this test it would be good if an error msg was shown and the print aborted.
The video https://photos.app.goo.gl/e78HytZowKtFqhjy9
The Z-axis is set to have a movement range between 0 and 22 mm and it is triggered ahead of time to not have it run into the print head.
In the video I tell it to go to +1 mm but each time I press +1 it moves to either 0 or 22 depending on what it was at before but it do not stop between those numbers.
