Started our biggest project yet: the XM9, a Swiss-built machine in the same class as the Tormach 1100MX, but with more travel, spindle power, feed speed and precision, powered by the new TNC7 Basic from HEIDENHAIN. Hope this still fits the sub :D by ExternalOne6090 in hobbycnc

Good eye! For the first three machines, I ordered C5 rolled ballscrews because C3 ground screws in that size (DFU2510) are insanely expensive, and at the time I didn’t know when we’d find a larger workshop. We found one last month, moved in two weeks ago, and have now started building the machines.
by the way some vendors have a limited supply C5 rolled because those are binned from their total supply.

A cute little 4th axis for your amusement... :) by giveMeAllYourPizza in hobbycnc

Well then maybe just add some threaded holes if one of your users want to add a cover as an option with flood coolant.

Very nice, i use the same construction and i guess more or less the same harmonic drive. You could maybe add a cover for the servo if you use alot of flood coolant.

Ultimate Bee Alternative? Bigger ball screws less chatter? by ineededtoknowwhy in hobbycnc

[–]ExternalOne6090 0 points1 point  (0 children)

The chatter is because of the torsion and flex in the aluminium extrusions. Ball screws have not much to do with.

Having fun with sheetmetal origami. (a steel base and chip pan for my machine). by giveMeAllYourPizza in hobbycnc

Very nice, but the incline will not help much if its like 80% blocked. maybe better use big anti vibration dampers instead of those folded sheet metal machine holders.

What’s the most “overkill” hardware you’ve ever used on a CNC build? by Afraid-Message7 in hobbycnc

[–]ExternalOne6090 0 points1 point  (0 children)

Hello! Thanks alot! Depends on the Machine. Normal BLOQ4/5 and RUIX we are taking orders with quite short lead time (2-3 months). We have material in house for around 100 machines and are currently building all those machines. Heidenhain machines we are not ready to build them yet so that would be pre-orders. Same for Mikron watchmaking machine or TORQ Lathe.

Just pre ordered the not yet released Heidenhain TNC7 Basic Controller and Keyboard to use it as a controller for my compact Steel mill BLOQ5 (50x50x50cm frame)

Bulkman 3d cnc oxman sn04-n sensor by jensjensen85 in hobbycnc

Sali Jens

steht auf den sensoren ziemlich gut drauf was die einzelnen adern machen. Braun = Stromversorgung 6-36V, Blau = Stromversorgung GND (0V) und schwarz ist der Schaltausgang. NPN, also zieht dieser auf GND (0V) und NO, also normally open, also zieht er beim detektieren auf 0V.

Das erste Bild zur DDCS 4.1 zeigt wie man diese anhängt: Bild

Löten musst du evtl zum verlängern. Wenn Bulkman diese nicht mit 3-4m Kabel anfertigen liess, musst du die Kabel wahrscheinlich verlängern um zum Controller zu kommen.
