MPCNC – New KRESS FME800q tool-holder with dust shoe assembly

First render of the new tool holder with dust shoe, connected at the bottom. The goal was to stiffen the spindle for aluminum milling and the transition to a more comfortable suction system as I don´t like standing next to it for an hour.

The clamp itself has already been printed and the vaccuum attachment is on its way. I will see how this turns out and if I need some kind of brush to bridge the gap to the workpiece or if the pure airflow is strong enough to keep the chips and dust under control. The spindle is closer to the gantry and sits firmly clamped by two M4 screws with washers and nylocks.

Sorry for the bad print quality, it is printed in PETG and I didn´t dialed in the parameters carefully as this is a plain mechanical part with no optical ambitions 😛

Those are my preparations for the nex aluminum milling test runs and the upcoming bigger project that might cause lots of dust.

Building a MPCNC

I started building a MPCNC router after I stumbled upon vicious1s design on thingiverse. I really liked the design and couldn´t resist to start ordering the electrical parts and the required conduit.

I took pretty long to get all the parts printed correctly, as my printer was modded right before the prints and it wasn´t to clear how it will perform. The MPCNC prints served well as a long time test of the modifications

I quickly assembled the parts I had so far to see what it gonna look like

First test fitting

All fitted very well, the conduit is stainless steel whitch came pre cutted. I needed to source some screws I had to use M4 for the most parts as M3,5 as suggest by Ryan was harder to find. After I got them it didn´t took long to get the majority of the CNC parts together.

Assembled stage 1,5

Great moment for me, as I coulnd´t stop thinking about anything else than finishing this nice little machine up. I made it 70 x 70 cm resulting in a build volume of around 40 x 40cm x 10 cm.

Next steps cover the electronics, base plate and the spindle. I will go for a Kress FME 800.
