Hi everybody
I have a Chinese CNC cutter, this a 2x1 meter table with three cutting head. This is not a milling head but cutting head to cut thin sheet layer. I am using this machine to produce ski, cut of base material (PE 1.2mm), glass fiber and wood(0.6mm)
The machine comes with a standard control software and this software is really poor and not so reliable.

Machine is connected to the computer via a proprietary card. Two cables with around 45pins and 27pins (approx !)
Machine electronics

• XY servo motor with end of stroke
• Blades rotation, also a servo motor with 0° sensor
• up and down for each head : control a relay to activate pneumatic fonction
• Stop and start program button

I am robotic engineer, I will manage reverse engineered the pin connection. This is not my concern.

I would to know if mach 3 is adapted to control this kind of machine. there is specific setting setting for this kind of machine

• blade adjustement, depending on the cutting length of the blade. The cutting point is not center on the rotation axis
• Cut is continous for small change of angle but blade should be lift up/down in a corner for example

Does this specific setting can be taken into account into mach3. I think this kind of machine is more similar to vynil cutter or plotter than milling machine

Is there people having expereience using mach 3 for plotter?

Thank you for your support.

Thank you, i found useful information how to configure mach3 for this kind of machine.
I didn't found information how to compensate for the offset. Offset is need because the cutting point of the knife isn't aligned with the center of the A axis. Any proposition to solve it?

It may be simpler to re-engineer your knife than to compensate for the offset,
Regards,
Nick

NORMALLY the offsetting would be DONE by your CAM software.

Just a thought, (;-) TP

Thank you for the input. I want to use the machine for production, me dream will be to set G code file for my production line and then operator can use it. If they need to generate new G code depending on toll configuration, for instance after a blade replacement.
Could be useful but I would avoid to adjust this in CAM software.

I have three tool using the same A axis but with individual pneumatic up and down and a laser positioning system. To configure this I can use Z, B and C axis to control up down. I also have to tool location offset for three the 3 tools.

I think I have to use a software dedicated for tangential knife than milling like mach3.

Thank you for the support.
