If it were EMI most likely it would happen on ALL kinds of cuts.. Detailed cuts can have more challenges if you are getting torch dives and bad touch off. The cheaper chinese motor drivers are...
It has to be paired with control software and hardware that can use the UP and DOWN to control the Z axis motor. MACH3 is one example. I think UCNC is another.
Its a MACH3 based controller. Gotta ask why though....MasterCAM is thousands of dollars unless you have a pirated copy. Its really powerful but not easy to learn. Plasma cutting is really...
One of the basic signals that help with automated plasma cutting is the ARC OK (AKA Ok-to-Move; Transfer. Arc valid,etc) Some plasmas have that signal, some do not (The ProCut does not). It's used...
This is really pretty simple: The e-stop input into MACH is getting a noise spike when the torch fires. All it takes is one short glitch to trip it. If the inputs on your BoB were isolated with...
The key is the POST. ITs a treanslator to generate the correct G-Code for a given machine. Either you need the G-code documents from Torchmate (Lincoln) for the dialct of G-Code the Accumove uses...
So you are going to try and use this for a plasma table? USB and plasma (noise) do not typically mix well. Can be done but tough to get the gremlins out/
So the whole machine is from China? ...
There are two important factors on a spur(pinion gear) it has to has to have the same PITCH (tooth spacing as the rack and the same pressure angle. I don't know about China but there are two...
Well the good news is you have a really good plasma cutter .
SheetCAM has INTERNAL variables and EXTERNAL (defined by you) it can use. That particular variable is set in the Job Options/ Rapid Height. 1.5mm is not much clearance for rapids
If you open...
Yes but if you edit it outside the Post Processor Edit button in SheetCAM it saves it in another location and you mi\ust IMPORT it to the SheeCAM library of Posts. If you change the name and save it...
Im confused. if you are using SheetCAM you can do everything in the POST including adding the values you want set in the UI in SheetCAM.
A touch off and lift to top of material , zero the Z and...
Yes, Your THC is sending an UP signal when it should not. That siganl (and the DOWN) should only come on when the Z is supposed to raise the torch . Signal from THC should only be active when...
How To Get Experience:
Get material.
Generate Toolpath from CAM.
Use largest diameter 2 flute up cut mill that will mill smallest features
Setup mister or flood
Make test cuts using...
You route thin aluminium. A good rigid table with a 2.2KW air cooled spindle with ER collets and using mist and air will cut up to 1/8" aluminium. We cut hundreds of plates from .060 AL and get...
14 ga WILL bow from both heat and stress relief....fact of life. I have seen 14ga popup 1/2" on the sides. The slower you cut the worse the heat warping will be. there is no way with ragged...
that waffle cut is not from cutting at the wrong speed. Grab your gantry and the motors with them on and locked and try to move it. It should have no play. Same thing with the cross axis. The Z...
The resolution of a machine is the smallest distance ONE step produces. That boils down to Steps per unit. You can't make a machine have more resolution that what the steps per unit are. Mach...
Precision Plasma has been a table kit provider for over 7 years. There are hundreds of his tables out and running.
The link to CYRious metal works is to a shop in Texas (that you can visit...
Do some research here and on other forums about Burntables.
I you want to have a USA built table with a solid warranty and good support then look at...
Glad its your project and not mine. Sounds like you have it all figured out. Good luck.
Not sure I understand this:
No such thing as a 25 pin RS232 Parallel port. Rs232 is a spefication for a single device to device serial and its SLOW compared to most other protocola, The 25...
Hypertherm has a host of patients for torch technology. You can see marked improvement just updating one of their older torches to the new Duramax. I don't know what kind of aftermarket torch you...
Rod: My intent was not to denigrate you or your work. I was only repeating what you have continuously posted and to support the concept that a builder can buy in at all levels trading time for...
Yep, But that pretty much describes any project from CNC to self-driving cars.. As they say...the devil is in the details.
Throw in the mix that the MP3600-DTHCIV is a complete solution. It includes the DTHCIV and all of its modules and a single cable interface to the Hyperthem or the choice of a Universal Connection Kit...
1. "Stick Building" = building something out of pieces, one piece at at time. What I meant was we don't sell parts and pieces. You either have to ignore customers that are doing their own...
That would be a question for the THC vendor.
It will not connect though the THC Sensor card that came with your THC300
