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.
Ohhhhh boy that looks sweeeeeeeeet !!! Really nice packaging !
Small update which marks the real start of my build :D
Laser-cut parts will be ready tomorrow. Sadly I have one "after work hobby funding project steel staircase" to finish next week so I doubt I can get any progress soon...
Managed to weld up the gantry today :D
So I'm all welded up and cleaned for painting. First plan was to weld it all together but ditched that wonderful idea. So now the frame consist of 5 pieces. Connections M10 bolts. Plenty of adjustments.
Next step is paint and then epoxy and assembly.
So now I should think about buying electronics...I have not done any research on this so please recommend! I will go with MACH3, DIY PSU, gantry squaring, home and limit switches. What BOB? Or even motion card? Drivers?
Thanks for listening!
What a beautiful work ! Seems like you've done this your whole life :)
I am not an expert but everyone seems to fit these kind of machines (steel based, roughly the weights you mentioned) with AM882 drivers (60-80V) (check out AliExpress for those, they are about 68 Euros free shipping with DHL, make sure to buy max 2 at a time or you will have to pay for shipping) with 3.1Nm Nema 23 motors from CNC4YOU (I tried finding them on AliExpress but 8 lead 3.1Nm 4.2A low inductance motors are hard to find elsewhere than on sites like CNC4YOU, Zapp Automation...). PSU I can't tell you yet as I am in the process of making one (helped by JAZZCNC). Ask the gurus and they will help you :D. For the BOB, I use a cheap chinese $10 one. Works good for what I need (5 axis, spindle on/off, spindle speed, limit switches, e-stop). That's even more than I need. Other people here will most likely tell you not to go with that and use a fancy BOB. I don't know much about BOBs so I stick with the basic cheap I've got :)
Looking forward to read other members' recommendations :)

Agreed, your work on this looks super sweet, should be a nice solid machine frame, nice one Toomast!

As I have invested a lot of time and money into this project I don't want to create unnecessary problems with cheap components. I know that lot of people use them and are happy but I don't want to waste any hour or even days for troubleshooting - just to find out the fault was the dirt cheap BOB ;)
Any other recommendations for BOB?
CSMIO all the way if you want a good one...Neil...
