Re: Duet WiFi temperatures are too low. - 7 Jahre zuvor

Hello, the firmware is 1.20.1RC2. It seems that the hotend problem was caused by the M572-parameter so the only temperature which is too low is the bed temperature as with the Duet 0.6. At room-temperature both sensors shows about 20°C. E3D-Thermistor for the hotend and china-Thermistor for the bed. Best regards, Sven

Duet WiFi - problems with interpolation. - 7 Jahre zuvor

Hello, when I enable interpolation the stepper motors stutters at small moves especially the Extruder always and the others for example at the front of the 3DBenchy. Are the motors not compatible or is there another problem? The motors wer equipped with the Micromake D1. Best regards, Sven

Duet WiFi temperatures are too low. - 7 Jahre zuvor

Hello, I switched the Delta to Duet WiFi, but now both temperatures shown are far too low. Especially PLA does not print @190°C because it is still too hot! Any ideas?

Re: Duet 0.6 Bed temperature is too low. - 7 Jahre zuvor

80°C means 63°C in real. 120°C reading means 103°C in real. 135°C reading means 117°C in real. The issue is most probably caused by the position of the Thermistor as it is far away from the surface. Both of my cores will be equipped with a Thermistor screwed into the aluminium plate but unfortunately this is not possible for my Delta.

Re: Duet 0.6 Bed temperature is too low. - 7 Jahre zuvor

That is not the problem as the room temperature is shown normally. However the Thermistor position is far away from the upside. It is integrated in the silicone heater. 8mm Aluminium with a diameter of 220mm and on top is a FilaPrint. I simply need to add 17 to the temperature shown, but how? BTW the heater cartridge is working well.

Duet 0.6 Bed temperature is too low. - 7 Jahre zuvor

Hello, the readings are far too low. I have a nearly constant offset of 17°C. How can I fix the readings? I tried the H and L values but this is not working properly. The problem is the setup. Silicone heater with integrated Thermistor, aluminium plate (8mm and a diameter of 220mm). Merry Christmas, Sven

Re: Bed temperature is hopping - 7 Jahre zuvor

I exchanged the bed heater completely but the problem still persists. So it seems that there is a problem with the Duet? Is it possible that the two pins from the sockets of the heater and the Thermistor may be connected? Next time when I remove the bed I will test it.

Re: Trapezoidal z-axis - 7 Jahre zuvor

Yes, but I have an idea to mix 2 designs from Thingiverse and the third part I designed, but I have no idea if this will work.

I did my OM2 from scratch. The spring loaded extruder is really a great improvement. Next step will be a TR8 leadscrew.

Bed temperature is hopping - 7 Jahre zuvor

Hello, if I try to heat my bed the temperature is irregular. Also if the temperature is reached it is changing by some degrees. Where I have to look for the fault? I use a silicone heater with builtin thermistor. Duet 0.6 from Replikeo. Best regards, Sven

Re: Fan control is not working as aspected - 7 Jahre zuvor

Yes I know. I had two faults. There were short circuits from the heater cartridge to the aluminium block and later from the Thermistor to it. As I saw smoke and detected the surface of the SAM was nearly liquid I knew it was too late. But hey, the web-interface told that there was a heater fault and the Duet was working until the power shutdown. I upgraded the heated bed to a surface that seems t

Fan control is not working as aspected - 7 Jahre zuvor

Hello, I updated my Ormerod 2 to Duet WiFi. I connected the part cooling fan to FAN0 and the Extruder fan to FAN1. Now the Extruder fan is often turnt off during printing and the part cooling fan is also not working very well. Slicer is S3D.

Re: mini height sensor triggering - 7 Jahre zuvor

I recently bought one sensor from makerdise.com and a second one is on its way. Could I have this problem, too? Should I check them? And how? I will use them about the end of the year. Before my OM2 burnt I could test it on black aluminium. The results were spectacular.

Re: Protection of analogue inputs of Duet Wifi? - 7 Jahre zuvor

Okay much better as smoke from the Duet and a really melted processor. But I will pay even more attention at the future the cartridge was old, so I did not believe there could be any problems with it and a Thermistor? I was soo wrong.

Re: Protection of analogue inputs of Duet Wifi? - 7 Jahre zuvor

I think I got it so that every version is somehow fixable. My 0.6 was smoking. The top of the processor was nearly liquid.

Re: Ormerod 3 - 7 Jahre zuvor

Hello, I use Fusion 360 I think you did not get the question. If I would change the direction of the heated bed to the z-axis it would not be an Ormerod anymore. That is why I am asking. At the moment I try to finish a CoreXY, but my Ormerod 2 needs more attention than I thought. Best regards, Sven

Protection of analogue inputs of Duet Wifi? - 7 Jahre zuvor

Hello, my Duet 0.6 burnt yesterday after I had a double fault. The heater cartridge was short circuited to the aluminium block. As I tried to tighten the nozzle the Thermistor must have been got in contact with the block, too. As far as I know the Duet WiFi is protected against such kind of fault, isn't it? Best regards, Sven

Re: Inductive sensor for Ormerod 2 - 7 Jahre zuvor

Hello Brian, you should read the description precisely. The diode is connected the other way round. So if the output is 5V there is no current as 5V is higher than 3,3V. If the sensor is triggered (if NO easier to explain) the output voltage drops to 0V. Now the current can flow and the input is also triggered.

Re: hobbed wheel - 7 Jahre zuvor

The disadvantage is that this part is only sold by very few shops. My idea is to bring it to easy available parts and to offer an Extruder which can be used also for other printers like Delta.

Re: hobbed wheel - 7 Jahre zuvor

I'm considering to design an Extruder with a standard MK8 gear as it seems that the Ormerod Extruder is the best I have found yet. But I have no time at the moment so it will be around 2017-10-03 until I can finish the design

Re: Ormerod 3 - 7 Jahre zuvor

The idea would be to support the arm at the front with keeping the shape as far as possible. A more stable frame reducing the problem of twisted rods and so on. I am wondering if this would worth the amount of work or if I should simply construct a simply design which will not have much in common with the Ormerod. Besides you could put the printer into a closet.

Re: X-/Y-Size does not match - 7 Jahre zuvor

It's strange. I used a test pattern of 102*102mm. I got a nearly good grid except for the outer area nearby x=-50mm and y=+50mm. The x side is bowed in. It seems that there is a mechanical issue but what?

Re: X-/Y-Size does not match - 7 Jahre zuvor

Many thanks for your answer. The best results I indeed got with a rod length of 211mm. I guess that is why Micromake used 210mm in Cura. For calibration I use an inductive sensor at the moment. I am not sure if a mini height sensor board would be more accurate.

X-/Y-Size does not match - 7 Jahre zuvor

Hello, I switched my Micromake D1 to 24V DC and replaced the controller with a Duet 0.6. When printing a test cube of 20x20x50mm I get a cube of 19.5x19.5x50mm. Which parameter is wrong? The strange thing ist that the diagonal rod length is 217mm measured and confirmed by others, but Micromake uses 210mm in Cura. Best regards, Sven

Re: Cheap chinese E3D replica print head - 7 Jahre zuvor

You cannot do nothing wrong with an original E3D V6 or a good clone. The advantage is that there a some designs available to mount it to the Ormerod.
