Is it feasible to relocate the workpiece between multiple modules? For example, when 3D printing, 1mm round holes are not round, and then transferred to CNC for deburring or CNC to laser engraving module for engraving? I want to make fixtures through the screw holes of the bottom plate, but I lack relevant dimensional parameters ---

To go from CNC to Laser, you’ll need a repeatable origin. The same goes for 3D printing to CNC/Laser. I have guides on making repeatable origins for the laser and CNC and have done combo projects. Laser: > [@Accurate, Repeatable Laser Guide](https://forum.snapmaker.com/t/accurate-repeatable-laser-guide/22779): > > My rotary guide (found [here](https://forum.snapmaker.com/t/multi-pass-rotary-guide/22121)) seemed to be well received, so I’m going to move onto the laser. This guide will be a bit shorter, as it’s not too involved, but is mostly to help increase repeatability, accuracy, and quality of your laser projects. Likely any machinist will say a repeatable, accurate origin is a key component in quality production. You gotta know exactly where you start to know where you’re gonna end right? I know the snapmaker method is just eyeball it, be it with a mark and lini… CNC: > [@CNC Repeatable Origin Guide](https://forum.snapmaker.com/t/cnc-repeatable-origin-guide/23596): > > Alright, this guide is going to be a bit more quick and dirty than my other guides, since it’s mostly a setup and has a lot of variables you can play with. I’ll try to supplement with pictures though! stuck_out_tongue Keep in mind, this moves milling to the lower left of the work platform, due to the lack of rigidity, may present issue on deep/stressful cuts that apply enough pressure to deflect the surface. However most work shouldn’t be affected. A lot of things are out of the scope of this … Combo project from the CNC Guide; [![](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/d/e/de467b4b26354a4cfac2e525c299ca059f365353.jpeg) ](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/d/e/de467b4b26354a4cfac2e525c299ca059f365353.jpeg) For 3d printing, you SHOULD be able to manage it if you load your model into your CAM software and match up your origin. I did this with laser when I was doing my Non-planar laser guide.

NOTE: This is not completely comprehensive, I’m sure there’s several ways to do this, including custom post-processors, custom tools etc. This is just the method I used and the examples within are very simple, more complex use cases can be done and may require tricks not outlined here.
