Hi All.
I am new to the forum and to the CNC project. I loved the design and I have printed all the parts and I am awaiting my Lead screw delivery before I can give it a test run.
I got my v-slot aluminium from ooznest, not that expensive if you want pre-cut clearance lengths so I bought 1000mm on the Y and 1500mm on the X. (obviously the cutting area will be smaller than this), (also makes it cheaper when it comes to leadscrews as you only need one of the longer more expensive lengths)
I ended up buying 2 x 20x60 for the X axis as it equates to the same as 3 x 20x40.
I have also had a go at a modification for a Direct Drive Z-Axis Modification which was done by slight modification to the rear top X-axis and then a modification to the Top X/Z Axis with integrated drag-chain holder and a slot design to feed the motor
Hope this is ok, Ill know more when i test it but so far it seems ok test fitting..
I've also made a modification for Z-Axis, but instead of placing it in top, I've placed mine between the front and read, with a modification in the rear.
I will post it soon in 3D design. Can you also post your .stl in the 3D design section of the forum, for those who want to make it like yours? Thanks ;)
Hi pinheaduk, are you not concerned that your directdrive setup adds even more weight to the front of the Z-carriage? It already has the weight of the spindle to bare and now you add the weight (albeit not that much) of the motor? Just wondering...
I always wondered why Topsie chose that design. Maybe a weight balance between Router spindle (front) and stepper motor (back)? I imagined that if it is too front-heavy the X-carriage would tilt just slightly and increase the friction (not what you want).
I like your modification much! Would you share the files?
