We’ve been looking at and test this issue all day and are able to successfully cut and run our test Crossfire and Pro machines with limits. That said we are releasing one more minor update to the firmware in case this is causing your issues. Please update your Machine Firmware one more time to receive it (there is no new version number).
In addition, we have noticed that with some strain the blade connectors of the limits can pull out of their connectors but not from the plastic sleeve. This can cause no issues if there is enough connection to keep the circuit closed but can cause phantom limit triggers. Please make sure they look like the below.
As a potential last option, can you provide some more information about the state of the plasma cutter at the time the limit switch is being triggered. Does the same trigger occur with the plasma cutter powered off (and THC)?
@langmuirsystems I reinstalled the firmware and checked my limit switch connectors as you stated in the last message but i am still have the same problem. It seems the m3 code is working as it should(the relay is clicking in the controller) but the torch wont fire with the limit switches enabled. I did a test with the plasma powered off and the program started like normal even with the limit switches enabled. As you can see on the pictures below i did recieve a error message i didnt get yesterday. Possibly the thc or plasma affecting the limit switches?
Just confirming: this limit hit (and subsequent alarm state) only occurs with the plasma on? This points to noise in the system causing these triggers. Is your Primeweld one of the newer style Cut 60s?
@langmuirsystems yes the plasma is turned on when the limit/error codes are coming up. My cut 60 might be a year old , not sure if that helps answer you question or not.
Just adding in here for reference, i posted the videos on Facebook earlier. Im running the RW45, resistor mod done, and table runs fine on dry run. Once the torch fires, it throws a hard limit alarm during the first or second pierce. Blade connectors are tight, and firmware was installed last night around 4pm.
I was going to do the L1 mod when i did the switches, but it was already a solder bridge. I must have recieved mine right after batch 2.
I have an older hypertherm powermax 30 same deal as RRyerson., but I have not reinstaled firmware since Saturday night, mine fires once then quits. Worked fine on dry run.
Will try tomorrow to cold tonight. UPDATE UPDATE updated firmware today and everything is working great. Thanks to everyone for fixing this quickly, this is why I bought, and would reccomend Langmuirsystems, also this forum is a great asset. Thank you all again. Merry Christmas.
My limit switch kit (ordered 23 days ago…come on LS!) came in yesterday. I installed it this morning, I will have an installation video posted this afternoon. It seems like if you hit zero work axis anywhere other than machine home you have to re-home your machine to get that back corner again, is that correct? I mean there is no return to machine home button so unless you zero your work axis to the machine home it will lose machine home whenever you hit zero work axis.
If you zero all work axes when set on work, you are not zeroing machine home. if you want to go to home after cutting toggle from work to machine and hit home. hope this makes sense.
