Thermwood Model 67 5-axis router

[hardipm]

We have a thermwood 67 with the Super Control 91000, based on a 1Ghz Pentium III motherboard.

I have installed the thermwood 5 axis post processor but am having a hard time getting the gcode when I select "Got continuous C-axis" is No, as the C axis of my machine is from 0 to 360 no negative and no continuous.

Could someone please help me guide as to what else needs to change for me to get the gcode.

Attached is a sample program that I am trying to machine.

I will have a Thermwood c67 with supercontrol 91000 controller in less than 2 weeks. I am also getting the post error, I will let you know if I get it figured out. How do you like your C67?

Thanks

I like it. But the operating system on my machine is very old. I hope the company updates it. Anyways did you get your machine yet and how did you make out with the post or do you have a better work-around to the problem?

I have a post working but there is a major bug I haven't had time to figure out. when I do 3+2 machining with axis 5 exactly at degrees(parallel to the table) it shift the whole coordinate system. I have used this post on a couple jobs now but its not great. Also, how do you deal with the shaky machine?  Do you have a fusion post working?

We are looking to purchase a Thermwood 67 and I am dying to know whether you guys got this figured out. Hoping I can save some money by not having to purchase MasterCAM, which is what Thermwood recommends.

What year and model of thermwood are you looking at? What are you planning to use it for. I can give you some advise. Also I may be selling my thermwood if interested.

It's a rebuilt unit from Thermwood, not sure what year it was originally.
Planning to cut large molds for thermoforming and using it to trim plastic
parts for the automotive industry.

What kind of tolerances are you expecting?  Our C67 is a 2004 5' X 10' X z36" My email is matt.colvin26@gmail.com maybe we can take this conversation private since this is regards to the post processor. 

I am still having issues with my "rev 2 post" machining 3+2 at 90 degrees but I haven't run the machine in 6 months so I haven't messed with it much. All my parts were complex so its not a big deal for me.

Not sure if you ever solved your problem with the orthangonal plane shift, but I had the same problem with a 5A router I built.   I found changing "allowedCircularPlanes = undefined" on line 34 of the template you posted to "allowedCircularPlanes = 1; "  it wil force everything to G17

I found where "undefined" = all planes, 1=G17, 2=17/18, 3=18, 4=18/19...

Hope it helps, wish I caught it earlier, the same problem haunted me for a while before I figured it out.

mhparks our issue turned out to be with Fusion360 before the post processor. Took like 6 months but on one of the updates it magically started working. I will look at your "allowedCircularPlanes" though. Thanks for the input!
