Reapply bed level in new gcodes. #21

Closed leoheck closed 4 years ago

leoheck commented 4 years ago

Hi, I am loading many gcodes to make one board, and after some time I cannot use the autolevel command again on the same board since there will be areas without copper.

My question is when I load a new gcode, does the cncjs-kt-ext apply the previously generated configs in Z-axis in this new file?

If not, is it possible to create a new command to update the be gcode with the later configuration? For example, it could be called something like "reapply_last_autolevel_config"

Hi,

I added this option, you can use it by issuing command: (#autolevel_reapply) need to update in readme still

Tnx for suggestion! This is a useful feature.

Really?! I was going to look this right now. You are the man!

I just have a question before starting tests.

Most of the time the same trill kit is used, and the drill can have the same size when in the chuck. But I personally have a misc drills brits. The end position inside the drill chuck can vary.

I would like to ask if this new feature is taking account of the new Z-offset to reapply the values.

For example, I will change the drill bit, then I can go to an area with copper to probe de Z-height again. Then I would like to #autolevel_reapply considering this new Z-offset.

I can also add it to README, I will make a PR.

Hi, for this after changing drill to another having different length, you can Z-Probe the PCB surface at approximately starting point (xmin,ymin) and set the Z WCO to zero again. This is what I usually do.

Another possibility may be to use G43.1 command (Tool length offset) - I did not try that so far

Tnx!!

That is what I was looking for, thanks. I will add this in the readme as well.
