Greetings Naijin,
That is a very professional looking build ! I especially like the low profile, rigidity and wide footprint of the gantry.
This should contribute to fine, stable performance.
You are to be commended and should be proud of your accomplishments.
Great work,
Russ

WOW, that is a very impressive build you have there cnc dick !
Very well deserving of it's own thread in the Show and Tell forum.
I'll split this post accordingly, feel free to post more details and hopefully, some cool projects produced by this fine piece of workmanship.
Regards,
Russ
