Re: Molten Terminal Duet

IMO you are asking for trouble with that much exposed wire on the VIN terminals. You should not see any exposed wire from the terminals. Best method is crimping ferrules and tightening the connectors properly. I use the same type of connectors (and ferrules) on mobile equipment and have never had th...

Re: Wrong temperature at the hotend

Adjust the Beta value of the hot end thermistor in the firmware.

Thermistors should be calibrated for the temperature range in which they operate in, and each thermistor can vary a little bit.

Re: Can't get level first layer/Convex bed

Adjusting the horizontal radius doesn't help. Probably because its not symmetric.

Yea, I'm suspecting that the only solution is to get a new bed. I can't force it to stay flat no matter what I do.

Re: G92 E0 causes a lot of extrusion.

IMO you should never home just one tower on a delta. If I tried that on my machine with the print head near the bed, I would expect that the X carriage would move up while the other 2 stay where they are, causing the print head to eventually hit a tower and cause the belt to start skipping. A better...

Re: Can't get level first layer/Convex bed

I've tried that multiple times, it doesn't help. I actually can't get the bed to sit flat while it is heating up. The force needed to flatten the bed starts to bend the melamine underneath.
It also doesn't help that the bed is more convex when it is heated up than when it is room temperature.

Re: v3 Maximum PSP Voltage Setting

Your heating time seems normal to me. I put a towel my heated bed and leave it for 10-15 minutes to get to 110°C, then another few minutes with the towel off for the temp to stabilise without the towel.

I've been having problems printing items that are bigger than 100mm, because I can't get the first layer to go down evenly. Its too thin in some spots, and too thick in other spots.

Re: PSU shuts down

Have you tried changing this value? #define HEATER_PWM_SPEED
That changes the PWM frequency.

Are you using dead-time for both the bed and extruder? I prefer dead time control for both.
And does your PSU shut off if you are only heating the bed?

This is the thread on the Repetier forum addressing the issue: m PDM is Pulse Density Modulation, and PWM is Pulse Width Modulation.

I'm having trouble getting calibration results, the best I have been able to achieve is a 0.11 variance using the calculator at Escher3d.com. Some of my probe points are +0.15 to -0.16mm, while others are acceptable (~0.03 mm.) I think part of the issue is the amount of play in the older V2 arms I h...

Re: stopping and resuming a print to load components

In your Gcode at the layer you need to add a component, add a coordinate move somewhere out of the way, along with a retract, and then add a pause command for X amount of seconds.

After the pause go back to the coordinates you were at, and undo the retract.

This should help you out: http://reprap.org/wiki/G-code#G4:_Dwell
