SHEETCAM ROTARY FULL
I have to build 2 of the square tube ones and will have to be full 5 axis machines as i need it to cut at an angle on some parts, the torch will have to rotate. And cutting any kind of design features messes the dimensions badly. It will have trouble on the upslope and downslope as the material will be at a very sharp angle and moving faster than when cutting the side. I did test using a 3 axis to cut square tube, and it does work if the Z axis and THC are very fast, but not good.
Since i have built several tube cutters for round tube, they are 3 axis machines and LinuxCNC does not care much that one of the linear axis is actually a rotary one, it works perfectly, and there is no need for THC at all if everything is set correctly.īut square tube has sharp corners and that messes up the material speed a lot making the use of the 4th axis a must, but again can be used without a THC.

SHEETCAM ROTARY HOW TO
Here is how to find the backlash of the floating head switch. The THC adjusts the cut height after the cutting is started. First understand the THC has nothing to do with the floating head, floating head finds the metal surface to set the pierce height.
This version is not the most recent but the functions it does have are thoroughly tested. Re: Floating Torch set up for sheetcam, mach3, and proma 150. However in some cases this can introduce bugs.

As SheetCam develops, more features are added. I saw that post about a month ago when Tom said something about cutting square tube.ĭo you think Les was talking about a 4th axes in terms of one rotating the torch as it rounds the corner? say you are cutting at 2000 mm/sec, my rough calcs says your Z would need to accelerate at 1000 mm/sec/sec to follow it. The links to the plasma and mill post processors for m圜NC from SheetCam have been added to the Downloads page of the website. If you have a good Z axis, I think it would be able to do it without crashing. It would be worth testing to see if the Plasmac THC can lift the torch fast enough to follow the surface. Just something to consider, best ask Les if you have any questions about it / his thoughts on the subject THC is best left off and run blind (no height control) with the z being controlled by gcode.
SHEETCAM ROTARY SOFTWARE
To prevent corner rounding, the corners can be looped.įor anyone working with these types of machines, we're sure you can see the benefits the features of this CNC programming software will have for many different applications.Here is a recent post from Les at sheetcam on rotary + square tube (4 axis recommended, you can normally get away with 3 with a rotary axis as you can repurpose one of the axis to drive the rotary motion device stepper)į/viewtopic.php?f=2&t=8458#p28054 As the small holes are too small to fit a full sized lead in and lead out, the leads are reduced in size to fit. SheetCam automatically works out the holes are inside so it reverses the cut direction for these features. The image to the right is a screen shot of an example part. SheetCam gives you many options to optimise cutting. Once you have defined you tool you can set up the cut. This increases consumable life and reduces faulty cuts due to blocked or obstructed nozzles Instead of plunging straight in, the cutter torch can ramp in, reducing the amount of material blown back into the torch.
