I've been in the sign making business for many years and use both adhesive-back vinyl cutters and large-format printers. THIS kind of project helps me understand a little more what is under the hood in each of them. I'm presently making the MPCNC. I will have to consider this as part of its repertoire. Thank you! :-)

Thank you for this thing! Thumbs up to you!

Hello Leo. Saw your YouTube video. AWESOME project! Just what I was looking for! I donated to you via "Tip the designer" and paypal. Check your account and thank you so much. I would love to hear about any updates on this project.

is it necessary to make changes to Marlin for the E axis ?

Are you drilling out the flange holes in the bearings to accommodate the M8 bolts? All of the drawings that I've found for the KFL000 show them only having 7mm holes.

It´s possible to add a 5 axis?

you can add 7 if you really wanted too.

Hi Leo69
I greatly appreciate your time and efforts in planning and building the mechanical details and the software development. Your product looks very promising and impressive. I believe I can use the MPCNC more effectively with this device.
I've started to print the items and they are looking so nice, already finished the Headstock and believe that by the end of this week the Tail parts will also be completed.
I issued all the hardware orders and have noticed that you were using Collar Limit Rings on both Head and Tail, are these just option or recommended items?
Also if you have any further new inputs/recommendations regarding this Rotary design I'll be more than happy to be advised.

Кто нибудь сделал? Может кто подскажет какие здесь шестерни? У одной вроде 10 зубьев а сколько у второй зубьев? И грм ремень какой длины и сколько зубьев?

Any way you can provide links for your BOM or at least let us know which sites you used? I'm having trouble identifying if I'm going for the right items.

Подскажите пожалуйста. "25XL037 10mm bore aluminum timing belt pulley" это ремень или шестеренка? Я как понял у вас одна шестеренка с 10 зубьями, вторая с 40 зубьями. Я правильно понял?

Thanks! If you find that you need more precision then there are plenty of affordable options on eBay too. The software I've attached will work with any stepper driven rotary.
