Re: High Speed XY Pen Plotter with Acorn Controller
That is a nice quick plotter. What is moving the pen? In my case since the pen pressure is controlled by a voice coil there is no specific stop needed since the plotter will only apply a fixed amount of force when the pen is down. Was your plotter done with an ACORN also or some other controller?

Re: High Speed XY Pen Plotter with Acorn Controller
I did get this working in CNC router mode. The Spindle speed is used to set the pen pressure and the Z axis direction output is used to control when the pen moves up and down. The speed it flows through the Z axis commands are set based on the lowest pressure setting. The voice coil controller worke...

Re: High Speed XY Pen Plotter with Acorn Controller
In this case I have an application that is top down for hardware--I can choose what I want to physically create pen pressure, calibrate pen pressure, etc. I am engineering those pieces to work extremely well. The software and to some extent CNC controller are more bottom up when it comes to actually...

Re: High Speed XY Pen Plotter with Acorn Controller
I am curious the best way to create this operation somewhat automatically when generating NC code from Fusion360. This is why I though I might include the PWM output as well. So for example I would set this up like a router and set it up with some nominal but very small z movement (G1 Zxx) for the r...

High Speed XY Pen Plotter with Acorn Controller
I am looking for some advice for setting up a high speed pen plotter with the ACORN controller. The XY movement is very straightforward and no issues there. In this case it is a couple of servos that drive cables that drive XY stages. It is capable of very rapid movements. I plan on creating the pri...
