I know this isn't the best way to go about it, but I am using inkscape and draftsight to design parts and things for my CNC plasma table. (usually just one OR the other)
I have a vector logo...
Could also be your voltage on the proma itself is set too high so that it keeps lifting to try and get voltage to the target area.
You can adjust the voltage on the proma on the fly to bring the Z...
Hey Eric, I am trying to create rules also.. more so to fix my hole quality on small holes and circles. > my plan is to create rule to slow speed to 60% and turn off THC when cutting, so the torch...
Just had to reload the license file and it works fine.
did you figure it out? I think mine was just a Chinese no name, I suspect they are all the same
Has any one encountered this?
I installed the latest sheetcam update a few days ago, that was it.
The part is not overly complex but probably over 180 line items.
This is for plasma table...
Can you tell the difference by looking at them? They are the ones that came with the machine. I assumed they were standard cut
I took the case off the machine and carefully did the same cut to see whats really going on. everything is set at book values.
test 1: THC unplugged and not hooked up, took voltage reading right...
Dropped the cut height to 0.06", much less dross and very narrow cut looks good.
This time on DC mode :) .. I got a reading of 1.84 volts
I uplugged the THC, multimeter set to AC volts - testing while cutting I got 0.48v red lead on pin 6, black lead on pin 5
65 Amps, 3/8" material, cut speed out of the manual. about 0.1" cut...
Thanks for the prompt reply's Tom and Jim
I will test pins 5 & 6 to verify 3.2-3.3 voltage range, and also j28- and j26+ if I need to dig deeper. - did notice the hypertherm voltage divider board...
I know this post is old, but rather than starting elsewhere.....
I have a hypertherm PM65 and proma thc. (1:50 voltage divider)
Hypertherm manual suggests 130v, 65a when cutting 3/8" plate.
...
I discovered I had the wires on the THC unit for THC GND, THC UP, THC DN mixed up. (bad wiring diagram for break out board)
It is working now, but I am experiencing another weird thing.
The...

Hi,
This forum is really great and I am finding answers all over, so thank you. :drowning:
I have seen this problem a few times and have not found an answer online.
My machine is cutting...
Thank you for replys I will try this.
Mike one question, how did you determine the oval looked like a bunch of small line segments?, did you zoom really closely into the part in sheetcam ? or is there another way?
Thanks Mike I will take a look for that setting in sheet cam
Here is are the .tap and .job files, I don't know what portion of g code you want to see, but there is 600+ lines so I didn't think I should paste it in here either.
Attached as .zip
Thank you
Thank you, I had to change values in Homing and Limit config.
I missed that before
Hi, I'm having an issue where I have a small piece of material say 12"x12" and my part is 11.5"x11.5"
I Ref all home and zero in the bottom corner of the material, but mach has my table work area...
I'm having an issue where I am trying to cutting large (15") ellipse and the arc portions are giving the machine trouble.
The machine is jerking around the corner and it is very noticeable on the...
Good News. I emailed Hypertherm directly off their main page about the dented case and Vince my local rep was very good about getting the details and drop shipped a new "housing" to my house. Free of...
Great! post any progress or info on setting up the unit. Im interested
Thanks for the info.
Mine doesn't look nearly as bad as yours. Maybe I should contact them and go from there.
I took pictures right away and documented.
I'm thinking the history log may be...
I purchased this brand new machine -Hypertherm Powermax65, and just picked it up yesterday. The store had to order it direct from the manufacturer, because they didn't have any in stock.
I know in...
Scary! Good luck, hard to know these days who is a professional BS'r operating out of a garage and who is legitimate. Hope all goes well and continue to update. Justice will be served in the form of...
