That’s the sort of thing I’m using on my Z axis [emoji1303]

Hi Harry,

I made the X & Y motor mounts myself using a hand router and some laser cut templates. It took a while and they’re not perfect but they’re rigid.
...

Thanks harryn. I’ve been told various different things from all over ranging from 1/3 to 125% of total amperage, hasn’t really made things much clearer [emoji1787]

I was aiming for 55V not 24V for...

Thanks Pete.

I’ve been pointed in the direction of this article:

This says I need 1/3 of the total amperage.

I know my motors are...

Is anyone able to shed some light on how I size my transformer for the motors? I have 3 x 5.5Nm Nema 24s and 1 x 4.5Nm. The motor data sheet says current = 5.8A and the driver max peak current = 6A....

I managed to get the rail straight within 0.01mm (0.0004”) using this method. I set the second rail by running the gantry along and tightening the bolts as I went.

Eh? You’ve confused my tiny brain, what are we talking about here?

Finally a bit of progress to report. It's taken way longer than I'd hoped to make up some of the aluminium plates for the gantry mounting but did the first fit up last night and I'm happy with how...

Whilst progress is slow on machining all the parts I need I have put together my attempt at the contrrol circuitry. I have to give a massive shout out to both ROUTERCNC & Joe Harris on the MYCNCUK...

It's about 4-5mm.

I’ve pretty much got all my hardware now(gantry extrusion, bearings, ballscrews, motors & drives etc), all I need is the machined parts to be able to start assembly - just waiting on my induction at...

Perfect, thank you!! [emoji482]

Can anyone suggest what size cable chain I’ll need for each axis please? Just about to place an order with BST and was going to add these to the order.

Got the frame as level as possible and poured the epoxy this weekend:

I’m going to construct a bridge between both sides and pour epoxy to level out any undulations in the box section.



I didn’t do anything special, just used the insert photo button on my phone...

Welding very nearly complete!! Very happy with how it’s turned out. [emoji41]

What stiffness are you aiming for? I’m intrigued to know what value you determine to be stiff enough?

Making good progress on the fabrication work [emoji1303]

Fair point about extrusion vs steel gantry. My original plan for making all the machined parts was to hand route them - I've seen people having good success doing this, I was trying to avoid having...

Thanks Luke, good points.

My original design was made up from two 80 x 160 extrusions in an L shape:

Hi all, thought it was about time to start a build thread on the Zone. I've been design ing my CNC router for a number of years, my progress so far has been documented over on MYCNCUK.com

Thi sis...
