Check your table OFFSET. It needs to be a bit longer on one side to compensate for the rouer / spindle to reach each edge.

Hello again,

I was wondering what thickness of the cable should I use for drivers? I have a several options, but dont want to overkill it.
What should be the profile of the cables.
About offset, did you mean the offset of the spindle? Here is the pic which could help.
I think I should move it more towards the end.

Marko, notice how the router does not sit in the center of the y-car. The table offset means that one end of the table needs more clearance than the other (ie the beams need to be longer) to be able to reach the end of your cutting area.

As to your answer on cable thickness I believe this thread holds the answers. http://mechmate.com/forums/showthread.php?t=2

but its usually around 18 AWG. (i think)

I made that mistake and later had to weld small pieces of beams to the ends thankfully I did not cut the rails to exact length of beams before I noticed the mistake.

You can use 4 core shielded, 1.0mm2 - 0.75mm2 per core for motors.
For the spindle 1.5-2.0mm2 should be sufficient

Very Nice 3D views ! I wish mine looks as good as yours.
Pre-mounting in 3D helps me a lot in the understanding of the MM pinciples.
I wish you the best for your build !

Thank you,

And it really does help a lot when you have something build in 3d, its much easier to understand where and how things go and connect.
With SW, i can determine the weight, very accurate measures so it can fit perfectly to the workshop.

Is there any benefit to use anti-vibrations feets instead of 100% metal ones ?

Dont know, but there is an option to add rubber bottom on these feets. If the vibrations turns out to be a problem.

Most people use them because they look sexy. Firm contact to the floor would be better in terms of cut quality. However, they reduce vibrations transmitted to the floor and reduce noise.

Good ! The cutting quality is the main goal, so I'll save money with simple feets,
which are 4 times cheaper. Thanks.

This is planning side ladder and fixing it up.
Below is my 1st weld done on that ladder. My experience in welding has reached for about 3-4 days, 1-2 hours per day. So I am pretty proud on that weld.
Rest of the welding is in the same or similar quality

Thanks,

That tool made my life much easier. Regreted tho for not buying 8 of them
Here are some pics from today work done. I have put it together just to get perspective. And it looks massive.



After working its important to clean the work area, coz my workshop is a bit small

DIY aluminium control box. To build it, I had to make a tin knocker/bender, which is made from MM parts. Proof of concept, and it works.
Control box needs back enforcement in the back panel with some 150x150x15 aluminum plates. Heating wont be an issue here .
Holes and ventilation will be drilled additionally. But so far, a decent box.

Yes, tempered glass for a spindle controller, and a hole for a digital thermometer.
Also, for buttons, and E switch.
Thanks for noticing

Nice box.
With the VFD in such close proximity to the motor drivers, I hope you have good grounding lay up later.

There's no problem in having a VFD that close to the drives.
My old machine was also mounted close to the drives, I had no noise what so ever from the VFD..

My new machine has 15cm more distance to the drives, and again, absolutely no problems with noise.

Not sure will I have noise, but I was thinking of making additional box for spindle control, with air flow connected IN and OUT to outside of the workshop, due the dust accumulation.
In the calibration phase, I shall see if there will be noise.
Also, I am looking for a good plan for a spindle mount, which should be made of aluminum.
EDIT: I am looking for cutting aluminum, how does a MM act in engraving and cutting aluminium.
Does my spindle speed @ 24000 RPM is 2 much to cut it. Would be the Z-car too light for a aluminium, and should I fill it with sand .

Marko,
Many have successfully cut aluminum on a regular basis. One machine, a 8' x 21' machine was built to cut primarily alum sheet for a boat manufacturing business here in the US.

Hi Sean, Thank you for your post. The plan was to work with aluminium and wood, and some softer materials, and lately, i was starting to doubt the MM can work on aluminium.
I saw some videos and I think I will be fine in that area.
