HEAVY: where do you see room for simple design improvements..? 🇬🇧
Let's all make the HEAVY (and V1) better without blowing the budget. What are the weak points in the design. Ok, I start.
1. each Y-Axis has only 2x V-Slot profiles. Maybe bump it up to 4x. More stable and more importantly, you can double the Roller count to 8x. The current situation with only 4x Rollers is bad - the Rollers will wear out quickly.
2. Consider using eccentric nuts to adjustment the Roller preassure
3. There are no axial bearings on the feed axes. The motor bearings are under too much pressure and will quickly fail.
@cheap: I'm doing mine with the standard V-Slot rollers, i think they are both compatible.
@PETER DONOVAN did you redesign some parts for the endstop?
Looking forward to the endstop-STLS ;)
Btw, does anybody know why @Topsie has placed the Y-Steppermotors at the front? Cable-length and management would be much shorter and cleaner when the Y-Steppermotors were at the back and the X-Steppermotor at the left. What is the advantage of the front/right motor placement?
No advantage to put it front, I did it like this to be easier for me to mount / unmount motors. in my small workshop my CNC is against a wall corner, and it's boring to move all the CNC table to manage motors.
You can put it in back if you want ! :)
Cheap it will probably be in about 2 weeks waiting on a few parts.
@Topsie: you wrote at the beginning of the post:
> The main problem today is the 2x Y axis rails, they are a bit to weaks and got some (very small) rigidity issues.
> I will probably design Y axis feets with a C shaped rails like on X axis.
> I notice this problem with the Nema23 version, Nema17 does not have the power to put Y axis in rigidity issue
Are you talking about the Heavy design or the V1? I also don't understand really what you are talking about. What are "Y axis feets with a C shaped rails"?
