If so, my question is can this output be restricted to just two logic levels, on/off, by LB? If so, I think I can design a small circuit (using a 555 chip) to translate on/off logic in to a two state PWM signal to drive the servo.

I’m not sure, but I believe this tool output level is used to control the power of a laser or other analog tools. That said, their controller hardware does provide an adjustable 0-10v “tool” logic level output.

It’s not clear to me yet if I am forced to use their CAM software (gcode generator app) to get proper gcode servo travel action gcode, but nonetheless I can’t use it because it is not equipped to deal well with hundreds of open ended vector paths - for openers. The Blackbox Grbl controller for ACRO provides a PWM output to drive a servo, but with limitations. I wish to adapt it for a large format pen plotter with gcode controlled up and down action for the custom pen holder I am designing/printing - via servo action. This machine config is used primarily for laser and 2.5D cnc apps. My ACRO 1010 does not have a Z axis connection. My question is, can I realistically adapt Lightburn to generate gcode for Blackbox to run a pen plotter via its Grbl firmware, with a ton of open ended vector paths, and do it on a Mac? As a result, I’m forced to look for a reasonably priced, workable 3rd party solution. (it has not kept pace with the latest Inkscape releases) Can’t use Openbuild’s CAM gcode converter app either because of issues with it handling open ended vectors. If you are wondering - passing an Adobe svg file thru Inkscape’s gcodetool extension might have worked in the past for simpler illustrations, but serious limitations and workflow problems with the current plug-in make it unusable for me.

Lightburn, I know how to convert an on/off in to PWM if necessary. The question is, can I use Lightburn by pretending the pen tool is a laser and incorporate/translate laser on/off action produced by Lightburn to drive a servo via PWM? If no PWM control available from. So far I have not found a workable solution.

This is illustrative work with hundreds (if not more) of mostly open ended line art which I need to convert and drive a fine line pen. I need a solution to convert detailed vector art I create in Adobe Illustrator in to gcode to drive the 1010’s controller. My application is basically very large format advanced pen plotting. Nevertheless, now I will explain everything you need to know about building a drawing machine like this, including how to design it, connect the electronics, what firmware and software to use and how to generate G-code for it.I’m in the process of putting together an OpenBuilds Arco 1010 with BlackBox for pen plotting now, and perhaps laser use down the road. I was actually surprised how good and precise the drawings came out, especially the ones where I used a 0.6mm gel pen. The work area of fairly big, 360x280mm, and the level of details this pen plotter can output is in my opinion quite impressive too. The brain of this CNC Pen plotter machine is an Arduino UNO board in combination with a CNC shield and three A4988 stepper drivers. It uses 3 NEMA 17 stepper motors for the X, Y and the Z axis motion, and a small servo for the gripper. The construction of the machine is based on my DIY CNC Laser Engraver machine from my previous video where the goal was to make the simplest CNC machine with minimum parts possible. In other words, the machine will be able to automatically change colors and so we can draw really cool stuff with it. “In this tutorial I will show you how I built a CNC pen plotter or a drawing machine but with one cool feature and that’s automatic tool change.
