The Precsion Matthews PM728V-T mill conversion kit is used for the mechanical conversion of the CNC mill build. Electronics and control box build videos are coming up in this series
Thanks for these excellent videos! I am about to embark on a CNC conversion using the exact same components that you have chosen. Could you supply the CAD drawings in STL format? Also if you do a future video on this topic, could you detail the counterweight system for the Z axis? Any spreadsheets or data that you are willing to share would also be much appreciated. I look forward to seeing future videos and your projects.
Hey Mike, I am working on getting a new domain to share prints and files - I lost the original - hopefully in the next week or two I plan to to do a short video on the counterweight system but probably not for a month or so - there is a lot of footage queued up
Awesome concise video about this upgrade kit. One question I have though, did you have to fiddle around to get everything to properly line up so they don't bind or was it really this straight forward? Might have to look if these kind of kits are available here in Europe for the mills I can get here. 🤔
Thanks for the comments - it is always hard to work out how much detail to include but I tend to want to keep things as concise as possible, even though it screws up the aggregate watch time for the RU-vid algorithm. The nice thing about a good kit is that the mating machined surfaces tend to eliminate issues with binding. In a later issue I will take a look at the backlash evaluation and fixes that I needed - the preload on the bearings and the gib tension turned out to be areas you need to pay attention to
This is the exact mill I want to convert. I did a conversion of an LMS 6550 with a kit and it turned into a bit of a nightmare. The kit was terrible. I want to design this one on my own. Where can I get the Fusion360 files you offered to share?
