Quite an Unusual one

[Boyan Silyavski]

Wow, 3 posts, it seems i had a lot to show and say

-the Z again, 2 spot welds to hold the side plates in place



-thats why i did not bother before too much rectifying the back Z plate. No i pushed it flat to the whole straight assembly, so all fell in place. Then spot welded CAREFULLY



-I know Dean, OTT and too much but that cost me only 30euros more. I promise never to do that again.



-squaring the Z in both directions against the straight edge that lies flat on long rails. this took a couple of hours to do it properly until satisfied



-another consequence of the mistake i made here





- That must be the most bad ass DIY Z axis i have seen on single gantry machine , OTT but make me proud and smiling when i look at it, so i assume it was worth it , did i say it looks like a missile ready to launch ?


See that big, no - huge mill vice? Thats a gift from Jeff for the build. have to rethink this and that for the bed. I never imagined i will have some day such a beauty. On other hand its not fair some people to have 3 of them

Well done sylyavski! That Z looks VERY strong, I like it a lot.

Watch out for ESD.

love this build! Any videos of it cutting yet?

Boyan Absolutely awesome build as per usual! Actually it qualifies as CNC porn I think! I am soo jealous well done!!!!

(Way off topic) One thing I worry about is the roof of your extension has no gutter! So all the water is going to run down the wall and into everything you have leaning or hanging on the wall. Am I missing something?

Oh and more videos or at least photos of chips flying when you can!!!

Maybe it's a case of the rain in Spain falling mainly on the plain and Boyan living in the Spanish mountains where it seldom rains?

The shop

SAMSUNG SERVO MOTOR DRIVER CSDJ-04BX2, CSMQ-04BA1ANM3 400W w/CABLE thats what i bought for Z

SAMSUNG SERVO MOTOR DRIVER CSDJ-04BX2, CSMT-04BB1ANT3 400W w/CABLE thats for the gantry

Now the first motor is shorter and fatter and the second is smaller and longer, more like a typical stepper. Both are ok. When buying servo motors and drives make sure they are 220V AC, motor is standard inertia and not some specialized motor for a special purpose, that drive works in STEP DIR mode, especially take care with Iskawa as not all will work ok for CNC control. Make sure you buy them with cables as 1 cable is >100 euro or more

I was between these and Panasonic/ a bit more expensive/ but decided on price. The best thing about these drives is Autotuning. You push the button and it starts jogging for 3 seconds and that's it-its tuned.

So my recommendation is the SAMSUNG SERVO MOTOR DRIVER CSDJ-04BX2, CSMT-04BB1ANT3 400W w/CABLE as it more standard size. and smaller shaft or servo motor plus automatic tuning.

Another good options are the Minawa /Panasonic series /


The other money wise option is Chinese servo drive drive MCAC808 and 400w servo: 60ASM400 which last i checked were ~180USD if you buy lot/4/ from Shenzhen Just Motion Control Electromechanics Co.,Ltd. Write to Molly/remove space/ molly @jmc-motion.com
Tell her Boyan from Spain send you there so my 30 email exchanges with her help you with the price.
I would use these motors in my prototype machines and hopefully later. These are probably the cheapest servos ever directly from a manufacturer. If you send me your mail i will save you needless conversations and send you some documents about these servos.

Hope that helps. There are other options but these are my conclusions as a balance of features and moneywise
