Re: ATX Power Supply - 8 years ago
QuoteKD0SKH aussiephil, I reduced the length of my original wires and supplied 6 wires to 11A connection and 4 wires to 5A connection, and everything works great so far, except for one annoying detail. My heated bed acts a little funny. If I go right for 90-100C, it tends to crap out around 82C and not take any power for a while (<60C typically). If I have it reach 80C through a few incrementby aussiephil - General

Re: Using a DC booster for 24V on the heated bed only - 8 years ago
Quoteicefire Of course, I could use a 24V PSU instead of the ATX PSU I have now, but that would mean to change practically everything: Hot end heater, fans, LED circuits, etc. Thanks for your help! Actually no, you could do the reverse of your original post, using a 24v -12v DC DC step down. your using a lot less current for fans, hotend, etc meaning a 100w step down unit would be heapsby aussiephil - General
Re: Lite6, ABS and PETG Skipping - 8 years ago
Whilst ABS may be slower than PLA, I completely disagree that it needs to be as slow as 30mm/s ... I regularly run ABS at 60mm/s between 232 - 242 depending on filament using mk10 extruders. With higher speeds you need to ramp up the hot end temp a little to keep the ABS flowing cleaning. Sounds more like you need to increase your extruder stepper current, if not possible then you have reached tby aussiephil - Printing

Quotedeckingman That's looking really neat. And small too, I imagined it was going to be bigger. I'll probably end up using short motors.

Re: Aluminum Sheet Between Heater and Glass - 9 years ago
Lets see 400x400 or 40cmx40cm size 6mm = 960cm cubed 8mm = 1280cm cubed 10mm = 1600cm cubed using 0.5W (maths is easier) 6mm = 480W 8mm = 640W 10mm = 800W My bead has around 2450cm cubed of 8mm Cast and with the 1200W heatpad it will get to 60c in less than 3 minutes from say 15c ambient but it also well insulated underneath so all heat goes to the bed. i've used Ceramic fibre paper in 3mm thby aussiephil - Developers
Re: ATX Power Supply - 9 years ago
Sigh..... lesson one At the currents people try to draw with heated beds over a small number of wires (in your case 4) you get stupidly high levels of voltage drop. If you going to do it at least use every single 12V and Ground wire to supply power. Power supplies will supply all the power they can up to the rating providing the cabling is up to it, obviously yours isn't if your bed stops heatingby aussiephil - General

Quotedeckingman Man, you are a star! Don't suppose you have that as an stl do you? No worries if you don't - I can cobble something together in OpenScad. Thanks for taking the time. I really think this, or something very like it, is going to work.

hey DM, I have around 4M of wiring to get to the thermister on the hotend of the Delta and my readings are consistent with a 3rd party measurement of nozzle temps.

Re: Help-What causes the auto calibration 6 factor to vary homed height - 9 years ago
Quotedc42 Sounds like the trigger height of the IR sensor has changed a little, and you need to reduce the G31 Z parameter in config.g by 0.1mm. Trigger height had changed, measured it about 20 times for a fairly consistent average around 2.62mm .... had already reduced G31 Z to 2.58 as with 2.62mm each calibration saw the homed height decrease by about 0.4mm Bed.g has been tweaked to ensure alby aussiephil - Duet

Here is a concept for a 3 way nema17 flying extruder mount that is suited to the E3D Titan...... first version allows for 48mm long motors which is excessive but I wanted to see the print size, 141mm x 131mm so will fit on most beds.

Back to basics What is covering your build plate, ie surface. If you still have kapton tape as often used on ffcp machines then the PLA will not stick.
