Plasmacutter 4th axis

thingiverse

Hello everyone, Today I'm excited to share with you a blueprint for a 4th axis for a plasma cutter that can be used for pipe cutting. The plates are cut using the plasma cutter, while the mechanics come from a 3D printer. You'll also need the following parts: 2 x bearings (https://amzn.to/2PuCpYG) 1 x copper weave band (https://amzn.to/32xlYQH) 1 x GT2 belt (https://amzn.to/32DvstR) 1 x stepper motor (https://amzn.to/2uzmBN9) 1 x stepper driver (https://amzn.to/2HY0vqT) 1 x jaw chuck 125mm (https://amzn.to/391rVIa) 2 x tension springs (https://amzn.to/3ac3gAV) - one for the belt and one for the copper weave band 1240mm square tube 50x50x3 80mm round steel d20mm First, all parts are cut out and printed. Next, four pieces of shape tube are cut to size and welded together as a frame. The round tube is then screwed to the base plate of the jaw chuck with a 3D printed gauge and welded from behind. The bearing holders are screwed on, followed by the attachment of all other parts. To begin assembly, pretension the belt tensioner slightly using the spring. Guide the shaft through the bearing, fix the bearing holder first, then the gear, and finally secure the last bearing fixation (as shown in the picture with the open cover). Finally, place the rear cover on and ensure everything is aligned. Clamp everything together, then drill and cut a thread into the molded tube so that the rear cover can be opened if necessary. The final step is to attach the earthing strap using a spring as shown in the picture. https://www.youtube.com/watch?v=Q3QpVNdWQNk *affiliate link: As an Amazon partner, I earn on qualified sales
