Steel Gantry Machine 1500x750x200

Yep just beef up the Ballnut mounts and your set to go.!
One thing I see is that you don't have much room for adjustment or alignment with that threaded bracket setup so give a little thought to how you'll do this for both directions. Ballnut housings tend to be easier to adjust than fastening ballnut direct to plate like that.

Those little white brackets sticking out on the end plates are those for triggering limit switches at each end.? . . . If so have you thought about using a traveling switch and save your self a lot of wiring and messing around with brackets etc. I do all my machines this way and it saves alot of work and easy to setup.

Thanks guys! Improvements implemented.

Yes these are brackets for limit switches. And I have not thought about using only one traveling switch!
Simple and ingenious - for sure I will also implement this!

I will go ahead and order my stuff from BST Automation.

Thats better.

I believe Dean meant 2 switches per axis, one wired home other wired like limit. With the benefit of all limits and all homes wired together respectively with the exclusion of the A home switch /second long axis/ which has to be wired separately, so you could perform gantry squaring

Are you using similar setup on your 1st build?

I will put 2pcs homing switches on both sides of gantry for squaring. And only single limit switch on long axis and make it traveling?

[Boyan Silyavski]

Yep, similar. As i described it above. Though tit did not come to my mind to use only one limit switch at Y,, anyway, i bought more than i needed.

I would say that the 4 most important things are:
-to drive them at 24VDC
-to mount them so that the head of the sensor is perpendicular to steel plate or whatever and body long wise in the same axis of movement
- shielded wire
- good quality flex wire not very thin, if budget permits same as stepper cable

What an awesome build ! I'd be interested to make the same one along the way ! Not sure if I did this right but I send you a PM ;) I'd be interested to make drawings from your model :)

Hi Eurikain,
Thanks for kind words! But actually all credit should go to users in this forum. Since all i have done is been reading and copying other build logs. I might as well could use Boyan Silyavski
1st build model ;) But I find it helps me better to truly understand my machine if I have at least drawn it from ground up.

Details from Fred arrived yesterday.
Excellent packing, fast shipping and all according to requested dimensions.
