First - thank you. Because I started a cnc build project using the same table draw sliders, without any reference. When I surfed the youtube I reached to your site as well. By knowing the possible technical errors for this sliders, it was able for me to rectify it.
the more I google the more unusual designs I see, Ive 3d printed mine with slide bearings and rods, but without a 3d printer I would probably go for a more expensive option of building the frame from extrusion and using linear rods, but the price would be much higher, somewhere around £300 in full unless you fetch each part from aliexpress on best discount
When I made the machine six years ago these mechanical components were still surprisingly pricy, and off-the-shelf CNC machines in the $1000 range. Then the 3D-printer hype kicked in and parts became cheap - now I could make a much better machine for the $300 I paid back then. Still proud of my build though :)
@@Joekutz Im currently building a modified 3d printed cnc from an old 3d printer, in general the design from Nikodem Bartnik, just with 8mm rods and without extrusions, will see how it will work, as first designed a full on 3040 all in metal and then decided lets try to build something a bit cheaper :D will make a video when cnc shield arrives, all the mechanics is printed and assembled just waiting for the brain
Meine Motoren haben 3.x Volt Nennspannung. (Der Wert sagt jedoch nur, dass man 3.x Volt Gleichspannung durchschicken kann, ohne dass die Windungen durchbrennen. Der Schrittmotortreiber sendet trotzdem 19V durch, da er soweiso via PWM den Stromfluss kontolliert).
martin2250 Thanks! There is no noticeable backlash right now in any direction. My precision is in the ballpark of 1/10 mm, I hope it stays like that. The sliders might wear out over time, so I may come back to that topic in a future video.
See video #2: One runs GRBL (freeware arduino Library for interpreting G-code), the other one my own software for controlling the machine with the keypad / LCD. One arduino is of course enough when one only wants the CNC functionality and control the machine via the PC.

What is the size of slider rail you used (in inches?
Looks really good. Thank you for sharing these videos.
Nice work!

thank you ! Your videos are awsome.
very good idea
eine Frage welche Nennspannung hat der motor 12v oder 3.45v ?
Meine Motoren haben 3.x Volt Nennspannung. (Der Wert sagt jedoch nur, dass man 3.x Volt Gleichspannung durchschicken kann, ohne dass die Windungen durchbrennen. Der Schrittmotortreiber sendet trotzdem 19V durch, da er soweiso via PWM den Stromfluss kontolliert).
achso ok ja weil ich möchte nämlich es auch versuchen eine cnc maschine zu bauen :D
Very cool build!
Did you measure the backlash yet? Also what resolution is possible?
This machine looks like it is great for milling PCBs.

Thank you good video very nice...
for what 2 arduinos?
See video #2: One runs GRBL (freeware arduino Library for interpreting G-code), the other one my own software for controlling the machine with the keypad / LCD. One arduino is of course enough when one only wants the CNC functionality and control the machine via the PC.
JoEtuuube
u are so kind
Thank's
