Re: Heat bed temperature anomally

The pull-up resistor needs to be 4.7 kOhm. It is placed on the motion controller board. It normally is. I know there is also a 10 kOhm resistor sitting on the heatbed. I'm not sure about the purpose of that resistor, maybe it is some check for disconnected cable, but I don't think it is included in ...

Re: Marlin 1.1.0 Unofficial firmware version 1.2.1.1

Git is a fantastic tool for collaboration and revision control. If you work professionally with Git, it is not a big deal to keep your own repository (with Raise3D perculiarities) up to date with the Marlin. You would add the Marlin repository as a remote, fetch its changes and then use git cherry-p...

Re: Marlin 1.1.0 Unofficial firmware version 1.2.1.1

To your comment on the Bed controller: It is not a good idea to use PID for the stock heated bed. That is why I have PIDTEMPBED commented out in my 1.1.6 firmware, like it is in the stock Raise3D firmware. This relates to the fact that there is almost no phase lag between the applied heater power an...

Re: Heat bed temperature anomally

Well, as I wrote in my posting, the beta_25_85 value for the thermistor used in the printer is 4100K and it has 100 kOhm at 25°C. This is basically all you need to know. If you have an ohmmeter, then you can measure the resistance of the thermistor and immediatly convert that to a temperature using ...

Re: Trouble with overhang printing

I have been printing overhangs with angles up to 74 deg, without support. The max. possible overhang angle depends on your layer height. I had to go down (locally) to 0.05 mm layer height in order to print 74 deg. overhang. I often use a layer height of 0.1 mm and overhang angles up to 60 deg. If yo...

Re: Heat bed temperature anomally

The easiest way is to use an ordinary ohmmeter, but whatever method you use, you need to know what type of thermistor is used in the heatbed. Raise3D printers use a thermistor like this one: NTCS0603E3104FXT, with a very specific NTC resistance curve. There are hundreds of other thermistor types. If...

Re: Heat bed temperature anomally

"PID tuning" was a bad advice anyway, for two reasons: 1. The priner is not using a PID regulator for the heatbed. 2. If it had been using ta PID regulator, then a PID regulator will never be responsible for a static temperature offset (there's an integral term in PID, that will always rem...

Re: Marlin 1.1.0 Unofficial firmware version 1.2.1.1

Maybe I didn't explain clear enough, but I have made the necessary modifications to the Marlin code of 1.1.6 to make it work with Raise3D printers, as I have done with earlier Marlin versions also. When I write 1.1.6 it is Marlin version, not Raise3D. What I tell you is that the code modifications a...

Re: Marlin 1.1.0 Unofficial firmware version 1.2.1.1

I have been using a Raise3D modified Marlin 1.1.6 for some time now, and it works just fine, i.e. in its standard configuration there is no visible performance difference at all to Marlin 1.0.2 (= official Raise3D). So really no point in updating, unless you see a use for the new features in 1.1.6 (...

Re: Raise3D ABS + XY Size compensation

No, sorry Zemlin, I didn't understand your system at first, because I didn't know that by "Offset Compensation" in Simplify3D you were in fact referring to "Horizontal Size Compensation", but that is clear now. I agree that this compensation can be thought of as an offset on all ...

Variable extrusion width.

I like ideaMaker very much as a slicer, but I still mostly use Simplify3D, because Simplify3D keeps adding new and extremely good features that ideaMaker (still) doesn't offer. In Simplify3d 4.0 we got variable extrusion width, called "single extrusion walls" and "single extrusion fil...

Re: Raise3D ABS + XY Size compensation

zemlin, if you can accept that nominal Ø3mm holes becomes Ø1.6 mm, as described in my example above, then I agree, that this feature can be used. If not, then you have to use X/Y compensation instead.

Re: Thermal Runaway Error in standby?

With the official Raise3D firmware you just need to avoid adjusting the temperatures in more steps. You can easily see the problem with the official firmware if you do this: 1. Set the bed temperature to 50 °C using the touchscreen and wait for the bed to reach 50 °C. 2. Adjust the bed temperature t...

Re: Problems with bottom layers

Raise3D PLA sticks very well to Buildtak. What is your z-gap (bed to nozzle-tip distance)? Did you check that your build plate is level? Although I think it is unlikely that your z-gap is larger in the center of the glass plate than in the peripheral, it should be checked. (z-gap is more likely to b...

Re: Raise3D ABS + XY Size compensation

I have argued before, that it is a misconception from Raise3D to put X/Y compensation in printer settings. The relationship between X/Y travel and the number of step-pulses is fixed, in the sense that one full-step is exactly 0.2 mm and one 1/16 micro-step is exactly 12.5 µm. The only parameter that...

Re: Raise3D ABS + XY Size compensation

Tinkerer, I think you are mixing up things here. I assume that you have used a heated bead when printing ABS, probably at 110 °C, as is normally used. Due to the thermal expansion of ABS, your model will therefore always end up be smaller than expected, when it is cooled down and removed from the bu...

As always, the Raise3D printer did a great job. This is a Lithophane Lamp printed with 0.1 mm layer height in black and white ABS. There's a 1.3W white LED bulb inside, giving 140 Lumen with nearly no heat, so ventilation holes were not necessary. This is my first printed lithophane and I'm really i...
