Hi,
its time to share some of the pics of my machine based on the Lowrider CNC. My intention was to be able to cut full sized sheets of plywood, 2500mmx1250mm. I wanted the machine to be easily disassembled to make room in the garage, but the XZmain pieces were falling apart after taking the whole assembly off the table. So I redesigned parts of the machine and used some rectangular steel tubes cut to size and welded everything together (I know it
s called Mostly Printed CNC, but for me this was the best way to go)
While doing this, I also switched to Nema23 steppers for Z and Y-axis, X-axis is still Nema 17.
Machine control is done by a SKR V1.3 and TMC5160 drivers, as shown in Teaching Techs videos- but it still took a long time to get this thing running.
Milling is done by a brushless spindle (if you want to buy one: it has to have tree wires coming out of the motor!) which works fantastic and is really quiet compared to other motors. I am using a cable drag chain for the X-axis and spindle cable.
The table, which is roughly 3 meters long, can be divided in half for easy storage and the legs can be removed.
I also came up with a super simple way to attach the timing belts, by using some aluminium brackets at the front faces.
At the moment, I am doing some test runs.
Estlcam 8 seems to work fine without any problems so far (I did some changes in the settings as mentioned somewhere her in the forum), but with Aspire 9 there are some issues.
I tried the Marlin_mm_test processors 3,4 and 5 and did some changes there too, I also tried to change the speed settings in Aspire and the current settings in the firmware, but still the z-Axis stops working from time to time, sometimes only one side, sometimes both sides, only to start working again after a while……
I checked the TMC driver- and motor temperature, connectors, cable, no result so far - maybe I just stick with Estlcam. We will see. Overall, I am quite impressed by performance of the machine and the accuracy which can be achieved with a setup like this.
