@mysta No flyback diode needed for the brushless pump. The pump has its control circuitry inside it. You can still PWM it and treat it like any normal fan, although low PWM values don't work well. I run it at 255 PWM, as there are certain audible ranges at various lower PWM values that are bothersome.
@3mm I was kind of at a loss too when I purchased my Smart Effector. Never owned a single E3D product. What I purchased that worked for me (from Filastruder) was:
Cartridge Style Upgrade/Parts that includes the Block, Thermistor and sock.
E3D heat-break v6 1.75mm version.
I can't remember if I bought the heater cartridge at the time or not, but I think I just reused my old one. I was at the point of switching from 12V to 24V too.
I already owned some nozzles that I knew would fit, but if you don't think you do, it might be another thing you need to add.
Hi, many thanks, all working nicely, I found a version of Marlin configured for piezo Z probe. Just had to invert Z min and alter rod length. Most impressive when working. A nice addition to my Linear plus.
The heatbed of this printer will be devided in 4 square parts with 4 heatbeds 400x400mm each, and each powered by its own PSU. Like this you dont need to heat the complete bed, when printed parts are smaller. And since the bed will not move, instead the XY gantry will move, the challenge is doable…
I presume you mean 1000mA and 1200mA (1A and 1.2A). Normal motor current is between 60% and 85% of the rated current of the motor.
Yes I ment 1A, forgot to remove the milli after the conversion. I've increased the current to 1.3A but it had no effect on the pattern.
I suggest you check that the carriages run freely up and down the towers when the rods and belts are disconnected. Unless they are extremely light, they should drop under their own weight.
I use the typical kossel carriages and they did drop of their own weight until i tightened the horizontal screw through them to lower the chance of warping in the Z-axis. It might not be needed anymore since I switched from the traxxis rods i used before.
Lubricating the magnetic ball studs may also help - I use silicone grease on them.
Gonna go get some tomorrow to give it try.
wouldn't build a KosselXL again with 2020 and use 2040 instead, which extrusions are you using?
Oh I'm using 1515 rods, which is one of the reasons i tightened the carriages. The carriages is printed in PLA and from what I recall the "handle" didn't flex that much but since I have a horizontal screw through it it cannot flex that way while assembled.
The Smart Effector is not protected against short circuit. The latest Duets have a fuse in the VIN supply to the fans, however it won't necessarily stop the fan mosfet from blowing if you get a short in a fan circuit.
The power supplies used in 3D printers are invariably short circuit protected, however that doesn't stop then supplying enough current to burn out PCB traces.
Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
