autoleveller with nonconductive material

[neptunier]

hi all,
i am new here, my name is michael and i am from germany.
i just got a copy of the 0.8 autoleveller software which works fine.
however, my cnc setup is a little different then the pcb setup. i use two probes, which are switches. one i put on the material to get the 0-point, the other is attached to the z-axis a little below the endmill.
when i autolevel, i use the switch attached to the z-axis to create the probe file.
then i create the gcode and use the other switch to get my endmill to the correct position. that works fine but i had to change the o100 sub to the following:

M5 (make sure the spindle is stopped)
M0 (pause for any probe wires to be attached)
G0 X#500 Y#501 (move to X Y position)
G31 Z-10.0 F200.0 (probe)
G92 Z#502 (set Z to position)
G92 Z31.55 (hight of probe switch)
g0 Z38
M0 (pause for removing switch)
G0 Z2

is there a way to put this into the software, maybe importing a .txt file as a o100 sub? otherwise i would have to change it every time and i already killed one switch with the regular o100

as i use a bigger working space (1000 x 500 mm) then a standard pcb the probe spacing in my case is 50mm. the autolevel processed gcode then adjusts the z hight every 50mm but a g1 x50 is processed into g1 x5 g1 x10 and so on.
is there a way to adjust the z hight every 5mm? i guess it would be a simple pythagoras calculation for the points between x=0 and x=50mm. probing every 5 mm takes a lot of time.

thanks,
michael

Hi Michael,

First of all, you should probably change the code there to:

Code: Select all

M5 (make sure the spindle is stopped)
M0 (pause for any probe wires to be attached)
G0 X#500 Y#501 (move to X Y position)
G31 Z-10.0 F200.0 (probe)
G92 Z[31.55 + #502] (hight of probe switch + set Z to position)
g0 Z38
M0 (pause for removing switch)
G0 Z2

otherwise the G92 line for setting the probe switch height will just overwrite the previous G92 line.

The idea of setting custom sub procedures is a good one though as I am not happy with how I have done it currently. Custom subs make it more flexible which is nice .

I think you mean, the height is adjusted every 5mm? Which is true, and you cannot change this value currently. I think you are trying to get the probe spacing to match this 5mm value, so where you want the probe spacing to be 50mm, you are changing it to 5mm to match more closely? You dont need to do this however, as the Autoleveller uses bi-linear interpolation and the height should be correctly adjusted anywhere is the 50mm square. It is OK to leave probe spacing at 50mm.

thanks for the corrected sub.
i looked again at my processed gcode. the first lines, he does not adjust the z height every 5 mm, it takes up to 30mm. from x25 to x30 the z height jumps 0.1mm. towards the end of the gcode every 5mm is a seperate z height calcalated.
here is the gcode:

Code: Select all

Firstly, You can put long code into blocks, and I have edited your post to do this. It just keeps the post shorter and tidier and I will add a sticky in the general section to explain how to do this and other things shortly.

The autoleveller will first break down long segments into 5mm sub-sections or 0.187 for inches so that each section can have its z height calculated. For example, a G1 line which is 13mm will be broken down into 3 parts, 5, 5, and the remaining 3mm. If a move is made where Z is above 0, it is not necessary to break this move down, which may be where you see large jumps.

The Autoleveller was originally designed for small PCBs and 5mm seemed like a good number to use at the time. For much larger files like yours, 5mm is probably too small and will result in much larger AL files. I will include the option to change this number in a future release.

I hope this explains something.

[neptunier]

i understand that the software breaks down the g1 moves into 5mm sections. the problem in my gcode is that in the first part of the code it does not change the z values every 5mm, see here:

N240G1X5.223 Z-0.9975F600
N240G1X10.223 Z-0.9975F600

N240G1X40.223 Z-1.0625F600
N240G1X45.223 Z-1.0625F600

starting at line? 250 it changes with every line, every 5mm:

N250G1Y4.135 Z-1.747743

N250G1Y29.135 Z-1.764301
N250G1Y34.135 Z-1.767612

that is the problem i wanted to point out. why is it inconsistent?

thanks, michael

[daedelus]

OK, I understand, thanks.

This is because the Y value is set to -0.865 above. See:

Code: Select all

N180(Toolpath:- Kontur 1)
N190()
N200G94
N210X0Y0F600
N220G0X0.223Y-0.865Z2
N230G1Z-0.9975F300
N240G1X5.223 Z-0.9975F600
N240G1X10.223 Z-0.9975F600
N240G1X15.223 Z-0.9975F600
N240G1X20.223 Z-0.9975F600
N240G1X25.223 Z-0.9975F600
N240G1X30.223 Z-1.0625F600
N240G1X35.223 Z-1.0625F600

Your probe area starts at X0Y0 so Y-0.865 is outside this probe area and so it doesn't calculate Z as well for those points.

If you want to fix it, you can always make your probe generation file cover a slightly bigger area. Start at X-1Y-1 for example. It should not make a lot of difference though.

[neptunier]

thanks, that solved the problem, i did not see the negative y value.

however, i found another strange thing. i had trouble converting a file with version 0.83 with a probe file into gcode. the result was something like 50000 lines of gcode, which did not load in mach3. and the autoleveller 0.83 did not close if i wanted to quit the programm.
i processed exactly the same files in version 0.80 and that gave me perfect results. the program closed fine.
i atttached the gcode file, the probe file and the two result files in a zip file.

does it matter with very big AL gcode files how many decimal numbers you have behind the point? you use 6, which is 1/100000 of a mm. does that need processing time in mach3?

thanks for your excellent support, i hope i dont annoy you with all these problems.

Not at all, we can point other users at these posts if they have similar problems so its all useful

0.83 breaks down arcs in the same way as it does with straight lines. v0.80 does not, it only breaks down straight lines. It seems to get stuck sometimes though and I have been working on this as a priority for the next version. I had thought the issue was with inch files as a previous poster had the same problem but after converting his original gcode to mm, it was fine. However, your file uses mm anyway and it still gets stuck, so there goes that theory. I am working on it though but maybe use v0.82 if you run into difficulties for now.

The fact that I use 6 decimal places is mainly for those using inches as units as you need a much smaller number to represent the same figure for inches as you do for mm. For example 0.1mm is ~0.00394 inches and with a PCB I want to allow as much precision as possible. 6dp seems to be a good compromise between accuracy and decimal places. So even though 6dp is used for mm as well, it probably isnt necessary to go to that extreme for mm, it usually doesnt harm anything either though.

thanks so much, so i wait for the next version and use version 0.82 till then.

i found another problem with circles
the circles do not get processed corrctly, they got a big bump. attached are the gcodes, generated with 0.82 or 0.80.
how could i prevent this?
