I quite like the look of the guiderail sets from Cloud Ray. But they still use a drive shaft and a single stepper drive.

One day I may get around to building one of my own

Third pic, one in the bottom looks to me somewhat like marking knife for woodworking...there are many designs. Some are to hold like a pen, some like a brush and some just liiks decorative, buta are actually hard to use.

Maybe it's for picking up litter.

Apparently white vinegar works for aluminium:


I too have ben working with some laser print transfer materials. I used to use standard HP printer with standard HP color cadridge and no paper would work with it. However brand print trancparency film worked fine, but need a clothes iron to transfer image. Standard laminator just does not have enough heat, I read from several sources that you need 180C to fuse the dye.

I still have the same old lasr printer and bought a new color cadridge, not HP and not the cheapes one, but mid priced generic. Transparency film does not work any more, but fun fact is that super glossy and coated paper works almost fine with a the same laminator.

I got some chinese yellow transfer paper and it seems to work most of the time ok. Not great for surface mout but ok with trough hole system.

I am thinkking of getting a 100€ T-shirt picture transfer press for this purpose, they should provide enough heat and pressure to get work done....or try UV option again...or try gardening instead.

Having repaired these type of machines for 30 odd years or more Iv'e seen a lot of carnage from just broken tooling and fixtures to repairs going into thousands.
Probably 25% caused by not proving the program on a first off. All it needs is a misplaced dec point.  Yes the first one will take a bit longer but in the long run it can save time and money and a lot of aggro. Some engineering places might take a chance,  but for the small business or hobbyist it can devastating.

 My lathe and mill are both manual and I've dropped a clanger a few times, it's worse if you do it after spending a few hours and cock it up on the last operation!
