Det er min mening. Hvor har du købt det set op? Det ser ikke hjemmelavet ud, men jeg spore kun en ting, er det stiv nok, med kun de to rund bare, for der er jo en side fors når du er moving on Y aksel.

Thanks for showing intrest in the project.
This set-up is my own ( Home made ). Unfortunatly no drawings or instructions are excisting. Done by my self and not expencive at all.
The white material you see is a 20mm POM plastic material. Given to me by a good contact.
A good and strong type of material very well suited for this purpose.
The round bars you see are 50 mm aluminium pipes just for stiffening up the main frame. ( 2 on each side )
The Y-axis is sliding on 2 ea. 20 mm steels shafts under the wooden table.
( not possible to see on the pictures )
on a ball bearing principple similare ( also home made with cheap standard ball bearings ) to the one seen on the picture ( X-axis )
The construction seams to be pretty stiff, but of coarse, I look forward to have everything mounted to it and see it running.
It should be easy to do modifications if needed.
Size of motors: Yes I have considered a stronger type. Nema 34 brand maybee.
The ones I have looked at has a tourque of 3 Nm, but I am very unsure wether this is enough.
My Y-axis is total 900m (Travel length is a bit shorther )
My X-axis approx 700 m
Maybe you have some thougths ?
If I am going up a step I also probably need to go for a bigger driver unit. ?
Maybe X and Y should be based on the 34 brand and the Z could be 23.
I assume the interface bord to the PC could handle different kinds of driver units.
