Torch raises during cut and pushes rip into the material THC pricecnc

Chuckweb · Post by **Chuckweb** » Wed May 12, 2021 2:45 pm

I have a Wrightcnc table with a hypertherm 85. My THC is a pricecnc. I’m running mach3 and sheetcam. During cuts the torch will start to raise a inch or two off the table. If it doesn’t do that it will push the the tip into the part and not stop. If I turn off the THC it works great except for losing a arc from time to time. Any help would be greatly appreciated.

When I say it pushes the tip into the part it only does it at the start of the second or third cut during a cut file. But as I stated in the original post everything works great when it’s all unplugged.

Are you using the Price post and do the Mach diagnostics check out as described in the Price manual?

Yes, when I run a file the “pricecnc post” is there when there when it starts cutting. It’s almost like it’s working against each other.

Has this Price unit ever work, is this a problem that just started happening? How old is it did it come with the table or did you buy it after?
I bought 2 price units and had no problems with either, still using one the other went with a table I sold. No reports of problems from the new owner.

I take that back, in the diagnostics when I activate output 1 pin 14 the led limit switches doesn’t light up unless I activate the up positive, up negative, down positive and down negative in the input tab. It works fine without the them activated until I hook up the price cnc controller. Do they need to be activated?

As far as I know it worked. I bought the table used about a month ago. The price controller leds light up like it’s trying to adjust the height.

Now if I go to the test option on the controller for the up, down and torch the motors just hum when I switch to the up or down direction.

I think you may have it wired wrong here is the manual for the Price unit.

Go through the section in the manual on setting it up and diagnosing with Mach3. If everything checks out we can move on. Also confirm your z axis is not slipping at the coupling.

I have it wired to BOB example 2.

The diagnostics is what gets me if I leave the active lows unchecked I can’t reset the emergency activation. Also I’m not using the 50:1 on the pricecnc I’m using the direct voltage and have me my torch activate 3 and 4 wired into the output on the BOB. If I have the active low unchecked the emergency button stays flashing. And when I go to outputs and check active low it doesn’t doing anything except activate my torch when I uncheck it.

I’m sorry I have torch wired to the NO and COM.

I have always used pin 9 for the torch on trigger, I know pin 14 can be used as an output but not sure how Mach can use it. I think that pin 14 is to be used for Anti-Dive signals. I as unable to find info on that BOB but see if the marking on the board shows pin 14 on the opposite corner of the board.

Ok, but that wouldn’t stop it from doing what it’s supposed to do right? If I turn off the THC everything works fine when I turn on the THC it wants to raise during a cut or it wants to push the torch into the material about the 3rd cut into a part. The first couple of cuts it comes down and touches the part and hits the micro switch and comes off the part and pierces the part like everything is working but after the third cut in everything starts going wrong.

have you tried the auto sense voltage setting?

if the torch is climbing or rising it means that the voltage setting is set too high and the torch is rising to INCREASE the sensed voltage to match the setpoint voltage.

if the torch is lowering or diving, it means that the voltage setting is set too LOW and the torch is lowering to LOWER the sensed voltage to match the setpoint voltage.

can you take a screenshot of the MILL OPTIONS tab, thanks

I did try last night but I couldn’t get the pricecnc to do anything. I pushed the knob in for 2 seconds and nothing happened. I’ll get you a pic in a few hours. Thank you

what voltage is it reading.....

are you set on 50:1 voltage divider setting within the pmx85?

Chuckweb · Post by **Chuckweb** » Sat May 15, 2021 12:20 am

It’ll start out at 170 then drop to around 120

Chuckweb · Post by **Chuckweb** » Sat May 15, 2021 12:22 am

Also when the torch pushes into the part that’s only during touch off not during the cut. I’ll try to get that picture we had graduation tonight. Thank you

ArcOk delay / voltage difference too small??

Also I just looked my manual over and I guess my AVHC10 doesn’t have auto voltage setting.
