Accurate Strong Gantry

[Boyan Silyavski]

Hi Vargai,
so you will go with moving gantry right? The way you have drawn the rails looks ok, but how you plan to straighten them and make them parallel?

Hi Vargai,
so you will go with moving gantry right?

I will go on with the Fix gantry system because it is properly fit to my goal -the moving bridge is a big advantage and present for me- so I am not restricted with a fix bridge height.
However I do not want to cut this line and leave it this way.-probably at a later time I will make gantry with this principle too.

The base frame version just idea for future project where the purpose and load let me use this principle.
Yes this is weak point of this design to achieve the straightness and parallelism
- correct more expensive method to machine it - can be done in one step w/o flipping the frame on the machine bed (drilling by DIY)
- DIY method -I am sure you will invent it
By the way I am wonder about the cost of the
epoxy system comparing to the machining.
If you have access to earn money in mean time with other job I think machining cost can compete with DIY cost Sum.
