My diy cnc project - have started mounting the base frame. 9090 and 4590 profiles + Bosh Rexroth 25mm rails.
Have ordered 1610 ballscrew for the x-axis.
This is great fun 
Now you’re cooking with dino droppings.
I have been looking around for someone with these larger extrusions handy. My rails use M10 mounting hardware. Do you think an M10 bolt and TNut will slide in the slot? https://www.aliexpress.com/item/20pcs-lot-M10-T-Sliding-Nut-Block-T-Slot-Nut-Aluminum-Accessories-4545-serie-Aluminum-Profile/32333403109.html

@Anthony_Webb search for Bosh Rexroth 9090 profiles.
My suggestion is to TIG weld each of the joints, once you have it setup exactly in each in their final position. The purpose is to stiffen up the frame, and to minimize any kind of flexing or movement. (Not to say I don’t like the saddle joints - as I do.) ANY flexing or slipping would yield dramatic, bad outcomes in your accuracy…

@jeremy_nothum I do not have welding tools
What controller do you guys use?
Should I use a ethernet based like this or LPT1 (LPT1 old?)

@Oyvind_Amundsen
There is another option. http://mesanet.com/fpgacardinfo.html But it is more than a stepper machine really needs. Although some still use them. If you’re interested I can probably hook you up with a company rep so you can discuss your options. I happen to know where he hangs out.
Check out MASSO
@Anthony_Webb A bit expensive
By the time you add up the controller, PC, software license, setup, etc. The masso is actually not too bad price-wise. I think I paid $515 at http://cnc4pc.com/htg5a1s-cnc-controller-1040.html
@Anthony_Webb
My controller PC cost me $12 total. That’s the tower, monitor, keyboard, and a mouse. I bought it all used. I run LinuxCNC as my controller software so that was free.
I’ve an issue with some statements they make on their kickscammer page too.
https://www.kickstarter.com/projects/hindtechnology/masso-the-all-in-one-cnc-controller
Really, it all sounds like bullshit to me. I don’t even know where to start. That’s the way of the world these days though I suppose? Run everyone else down in order to build yourself up.
I’m sorry but I cannot in any way support the efforts of people like that. Can Masso even run Delta robots? LinuxCNC can.
Get a real machine controller already.
@Paul_Frederick what controller do you recommend?
What is a OK controller, driver and psu (voltage) setup? I consider 36V 12-15A PSU.
Have been told this driver is ok?
Anyone tested it?
@Oyvind_Amundsen
It depends what you are looking for. I just use a parallel port because it is cheap. I’m looking for economy. If I was looking for higher performance I’d go with a Mesa board though. Mesa costs more, but it is a large performance improvement too. I think you can get a Mesa kit for around $179? Although if you talk to PCW he can tell you exactly. Let me see if I can get a hold of him and ask him.
Hmm, a rare time when he’s not on IRC.
I have a project where I`m going to test the RADDS controller (http://doku.radds.org) + External drivers running Repetier FW/Host - I do not know the result, so that is a seperate project.
@Paul_Frederick I’ll consider it, What software does it support?
@Oyvind_Amundsen
well, it is your typical Chinese advertisement. So it is riddled with inaccuracies and omissions. But from what I can see there is good, and maybe not so good. Two things that really concern me is a lack of quarter stepping mode (an omission? - preliminary data sheet confirms lack of 1/4 step mode) and no stated setup timing. According to the Internet the drive IC on this board may not even really exist? I’m having some trouble locating a bonafide data sheet for it. All I can find is a development proposal. I can’t even find a signal setup time in this proposal sheet. So it is a quality that is being glossed over with this device. Everything has a setup time. What this device’s is, is anyone’s guess too. But that is critical information.
The engineers slept through this class
