program freezes on gcode generation #651

Closed jmartens2 closed 2 years ago

jmartens2 commented 2 years ago

im really sorry. my issue doesnt allow me to save after gcode generation. basically the program freezes at 100% of generation but doesnt offer the tabs needed to move file or any thing. ive tried different file formats, changing settings, shutting down my macbook pro 2013 with 8 meg ram, once or twice if i reset to factory itll work again. today isnt one of those days. could you please give a guy a hand

jmartens2 commented 2 years ago

i sorry about the open and close of issue. i must read instructions better.

harlock999 commented 2 years ago

I'll do my best to help. What do you have in your GCODE setup? Which GCODE function are you trying to perform?

jmartens2 commented 2 years ago

marlin. sorry but been all over internet trying to make this work. it worked for a while then started behaving funny until it crashed.

harlock999 commented 2 years ago

I have no experience with marlin but I am not sure how this can affect the GCode compilation.

harlock999 commented 2 years ago

Also, when I was asking about GCODE setup, I meant the TOOL ON and the like. There's a known issue when combining the INTENSITY variable and some Laser raster functions. For now I believe INTENSITY should only be used with Laser Cut.

jmartens2 commented 2 years ago

yes ill try different file im unfamilar with nodejs i will try clearing cache ran first aid this morning tool on is m106 p0 laser intensity is set to S forgot to say thank you

jmartens2 commented 2 years ago

simple jpg generates i found that in tool head beam was set to 0.2mm the program gives message that 0 and 1 are closest values. could this be problem?

harlock999 commented 2 years ago

0.2mm is quite reasonable value, but I vaguely remember something about some similar message in the past. what happens if you have it as 1 (just for testing)?

harlock999 commented 2 years ago

Also if you are using a simple JPG, I'm assuming you are doing raster engraving of some sorts?

jmartens2 commented 2 years ago

i think beam size in machine settings has to match in gcode laser diameter? and it has to be 1 or 0. i will update. thank you so much for your help so far i love this program

jmartens2 commented 2 years ago

thank you again. as long as i leave it at 1 it will generate gcode. as i burn the project it leaves the lines too far apart, is the a way to bring closer together? horizontal lines.

harlock999 commented 2 years ago

Something is going on with the error checking as 0.2mm would make the lines closer. Can you try to put 0,2 instead of 0.2mm? I have seen at times on other software that the decimal dot or comma aren't interpreted correctly.

jmartens2 commented 2 years ago

i shall try. what should the beam size be in machine settings? it wont take a comma in laser diameter.

harlock999 commented 2 years ago

It depends on your machine, optics (distance between focal point and stock material) etc. I believe 0.2mm is a good starting point. I'm digging in older threads over at Maker Forum and this is the link I was thinking about regarding $INTENSITY: https://forum.makerforums.info/t/laserweb-raster-gcode-generation-stucks-at-100/85470

But it looks like you have something slightly different. Do you know how to bring up the developer console in your browser?

jmartens2 commented 2 years ago

0.2 crashes at 97% no but i can google

harlock999 commented 2 years ago

If you have something weird in your GCode setup the GCode processor may not like it. You may have an extra space or character at the wrong place. You can try to create a new machine profile and carefully re-enter your settings.

jmartens2 commented 2 years ago

as long as i keep the laser diameter at 1 it generates. i will create a new profile. i hate to keep you from doing things but thanks

jmartens2 commented 2 years ago

im trying to make a new machine profile and the old settings are populating the boxes

harlock999 commented 2 years ago

oh? I don't recall this behavior, but then it's been a while I haven't tried myself. Make sure all the GCode settings are cleared and retype them.

jmartens2 commented 2 years ago

working on it.....

jmartens2 commented 2 years ago

this is strange. as long as i leave laser diameter on 1 it generates a gcode. im going to set this down for a while and pick up later. time to do my chores according to the boss of this house. thank you so much for your help so far!!! back in a while take your time to enjoy your day!

harlock999 commented 2 years ago

np, I believe next step is opening the developper console in the browser and see if you get any interesting message there.

cprezzi commented 2 years ago

"Laser diameter / Beam diameter" just tells LW how big a pixel should be and how far the scanlines should be from each other. This should match about the width of an engraved line. 0.2 is a good value for a CO2 laser. (Don't use the up/down buttons of the diameter fields, as they only increase/decrease by 1)

This value also defines how much data will be created. For example, if you have a 100mm by 100mm picture and 0.2mm beam & laser diameter, it will create a point for every 0.2mm which results in 500 lines x 500 points (= 250'000 points). An image of 200 x 200mm would already produce 1000 x 1000 points (= 1'000'000 points)!

This is the reason why bigger pictures can reach the available memory limit. In such a case you can:

jmartens2 commented 2 years ago

Those are some of the things that I’ve been trying. I’m currently down to .3 mm on laser diameter. It takes a little bit to generate. Is there a way to elevate the available memory that the program can access or is that tied to my machine (laptop)?

jmartens2 commented 2 years ago

Oh my manner are terrible. Thank you for your help here on this project. You’ve given me a ray of hope, I’ve been floundering in info on the internet about engraving and no real help. You guys are amazing.

jmartens2 commented 2 years ago

Hi I’ve been able to get to .2 mm on my laser diameter. It takes a few minutes to get there but I can live with that. another question, does using the filters for the generation affect the gcode generation? Say greyscale, does it add to problem? Also during these trials I’ve realized my beam setting in machine is set to .1 will this also make the program work harder than if it’s different from laser diameter or do they provide separate results on generation?

cprezzi commented 2 years ago

I don't now if the filters make the memory problem worse or not, but I usually prepare the image in a photo editig software anyway to convert to grayscale, optimize contrast and adjust the resolution to match the needed pixels. This way you don't provide a larger image to LW which uses more memory and could create aliasing in the scale down process.

The "Beam diameter" from the machine settings is the default value that is copied to new "Laser Raster" operations. Only the value in the operation is used for the gcode generation.

Unfortunately there is no possibility to increase the available memory in LaserWeb. This is depending on your PC and the used Electron Builder Library (for compiling an executable).

jmartens2 commented 2 years ago

Thank you for all the hard work on this project. by needed pixels, how does one come to that number to be used?

cprezzi commented 2 years ago

You can calculate like this: Size you want in mm divided by laser diameter setting = pixels

Example: if you want the engraving to be 200 by 100 mm and use 0.2mm laser diameter, you would need a picture with 200/0.2=1000 pixel by 100/0.2=500 pixel.

jmartens2 commented 2 years ago

Is there more resources for using this with engravers? Or photo prep?

cprezzi commented 2 years ago

There is some documentation on our website: https://laserweb.yurl.ch/documentation/cam-operations/40-laser-operations/8-laser-raster-settings And tere are lots of infos on google and youtube from other people about picture engraving (not specific to LaserWeb).

jmartens2 commented 2 years ago

Thank you again
