Benbox Laser Machines/CO2 Lasers/3D Printers

I'll have a look at this.

That sounds about right. BCL has not had any updates in awhile. BCL laser can be used for cutting as well as engraving. Just like T2 can. Both have trial versions. Use both and then decide which one you like working with.

George (@ggallant571) hit the nail on the head. This type of calibration is best handled in the firmware, not in CAD/CAM Software. BCL software (as well as T2) can send the g-code configuration settings to the laser machine, but, as George pointed out, if you need Double data type precision vs Integer precision, that has to be handled in the firmware. BCL and T2 cannot force Double data type precision on the firmware if it wasn't designed for it.

Hi
My cutting is about 0.2 % off what is in DXF file. Does the Bencutlaser has a motor steps length/distance calibration ability ?

BCL does not have that capability. Make absolutely sure your laser system is rigged correctly. Belt tension, all nuts tight on the wheels and elsewhere, etc. If you machine is rigged correct, you should be able to burn pretty accurately. 0.2%I would say so, so check your machine carefully.

This post should have been in the BCL Software section else I won't see it. I just happened to spot it but I don't read every post around here outside of BCL Software. Unless you meant the Benbox software which is vastly different from my BenCutLaser (BCL) software.

The videos you should look at are the ones where you create a laser tool for a specific job. In your case to cut 3mm wood. Name your tool accordingly.

Then calibrate if by seeing what settings you need to cut 3mm wood. You'll want 100% power. Test burns/cuts will determine the best speeds per grain direction. Use the square test patterns to test your cuts. You'll need about 5 to 6 or so passes to cut 3mm.

Remember once you get your laser tool setup, that's your tool to cut 3mm wood. Don't change your settings and don't use that tool to cut any other type of wood. Each laser tool your create should be for one specific job only: cuts, surface burns light or dark, etc.

I did test burns using the test shapes when I had my laserbot but I don't have it up and running any more.

A z axis won't help much with a 1.6 w laser. I have a z axis with my 1.6 and it's not worth the effort in my opinion.

A blower is a highly desirable option to have. I recommend installing one to blow the ash away for cutting.

Obviously you should not see any gaps in your burns. This is a laserbot problem. I don't normally use a laserbot and therefore I don't see this problem. Do you have another laser system available to test with?

What timezone are you located in? We need to do a screen share so I can see how you saved the toolpaths, etc. We can use join.me. Let me know what times work best for you today.
