Ok, it's been a while since I posted, doesn't mean I stopped working on the machine! One thing that I found is that I often open my coolant bucket to ensure the coolant is flowing. So I decided that designing and machining a flow indicator would provide a good opportunity to experiment with full depth cuts / adaptive cutting vs slotting and multiple side machining. I already machined the part last Sunday and will post the finished pictures tonight along with comments
It's been a few days since my last post. I made a lot of progress on the construction of the milling machine. Design and printing of various brackets and panels https://youtu.be/cpSZCr0v9j8 https://youtu.be/Jzw_BS4OWUU https://youtu.be/PUjdCl345Lk I used T-Nuts + M5 screws to assemble the drives on the machine frame. I also installed a wires guide to keep everything tidy. I'm not sure how it going to hold up in regard to vibrations but I'll wait until the machine is up and running before making my mind. I'm trying to keep the electronics embedded in the machine as much as possible. I then assembled and wired the power panel. I wanted to have separate switches for the the control / power sections. ...
I received my replacement Azteeg X5 Mini V3 today (2 days delivery from USA via DHL) Installation was a breeze, same connectors / pinout as V2. I grabbed the latest firmware on GitHub and checked my config against new V3 (enable pins are reversed). Installed the jumper for microsteps (1/32 on all axis, 1/16 on extruder) and added heatsinks. Everything seems to be working properly so let's try a print! To be continued.... ;)
Well, after a year of trouble-free service, my 3D Printer finally broke down yesterday. It started with an airprint https://youtu.be/QYAPWH0TTHg First thought was a fried coil in the extruder motor : the motor is a small 0.5A stepper that need active cooling to prevent overheating. However, I was surprised to find that both coils where ok. Next was a check on the controller driver output : I swapped the connectors of the gamma motor with the extruder (after lowering the current to 0.5). The extruder motor ran fine but now the gamma motor was dead. So my diagnostic is that the driver failed on my Azteeg X5 Mini V2, which unfortunately have a glued on heatsink for all 4 drivers. I will contact Panucatt today about how to fix or replace the board. They now h
I took a order to 3D print the parts for an OX Metal Build (http://www.openbuilds.com/builds/ox-metal-cnc-router-mill.3681/) I'll add pictures and videos to this post as I progress Update Feb 12 : All done! Here's some videos : https://youtu.be/C8yyEvJmFhk https://youtu.be/vujnDj51SpI https://youtu.be/mls0q_Qldwo
