Re: First N1 screen stayed on, now it won't boot

I bought the replacement display assembly, which comes with a display and the other PCBs. That has fixed the problem.

Re: First N1 screen stayed on, now it won't boot

I tried unplugging the battery and powering the machine up - no difference. The LED backlight is on, but nothing happens on the display and the motors don't move. The power supply checks out okay with 24v present on all red terminals. I just changed the main pcb for a known good secondhand board and...

Re: First N1 screen stayed on, now it won't boot

Hi Steven.
Yes I have a multimeter, where do you want me to measure? I have measured the 24v supply to the touchscreen board and it's bang on 24volts

Re: First N1 screen stayed on, now it won't boot

I have stripped it down, made sure all the connectors have been re-plugged a couple of times and re-built it. When I turn it on all the fans start up the LED strip light comes on, the display backlight is on and the little blue LED on the control pcb is on. But that's it. No movement from the motors...

Re: First N1 screen stayed on, now it won't boot

Does anybody know what the power resume board actually does, in electrical terms? Mine seems to have 12v in and 3v out, is it charging the battery? It has 2 green LEDs, are they supposed to be on at any stage, because mine aren't?

First N1 screen stayed on, now it won't boot

My N1 printer behaved strangely last night, when I turned the power off the screen stayed on! It was displaying the same stuff as usual but obviously running off battery power. Of course, it didn't respond to any key pushes. It was gone midnight so I just walked away and left it. This morning the di...

Re: ABS printing

I only ever use supports as a last resort; can you eliminate them through design or positioning on the print bed? When I use PLA they mostly work okay, but with pretty much everything else they are difficult to remove and leave a rough surface behind. Fine tuning the settings does help, but takes ti...

Re: Sizing to design

There are no hard and fast rules but, assuming you are starting with a calibrated printer / filament system... External dimensions won't vary by too much, internal dimensions will usually be smaller than your design. When I'm designing a 20mm pin to be a close sliding fit in a 20mm hole I would star...

Re: Ideamaker - Add Date feature request

Why don't you just add the version number to your template name? e.g. N2-Speed version 7

Or the date? - N2-Speed 25/9/20

Re: strange clicking sound while extruder moves

... as it pulls down the filament, it will skip but not all the time. Solution please as it results in under extrusion? The extruder is just a pump. When it's pumping the filament there is a certain amount of force required. If that force is greater than the extruder mechanism can supply, something...

Re: Using Ultimaker Cura with a Pro2

Why would you want to? What features/performance advantage do you expect to gain from using Cura? I'm not saying that ideaMaker is the best thing since sliced bread (pun intended), but I find it feature-rich, intuitive for the most part and fast. I particularly like the remote camera feature and the...

Re: Temperature Sensor Error

I would suspect the connections to the board. Try gently unplugging and re-plugging the multi-colour wire connector a couple of times. Check the connections to your thermocouples while you're at it

Re: Using a micro switch as a filament run out sensor.

I'm planning to add filament runout micro switches to my printer and have done a fair amount of planning, but I haven't made it yet. They need to be 100% reliable, tolerant of subtle differences in filament thickness and surface texture, whilst not adding any noticeable friction to the system. The R...

Re: Four percent shrinkage with PLA?

In my experience, the dimensional issues with 3D printing are realised regardless of shape. The limitations of the software & hardware and the physics & chemistry of the plastic all contrive to give me less than perfect accuracy. But it's consistent, internal features come out smaller all th...

Re: How to avoid distortion on large flat models

I agree with Jetguy, it looks like the shaft is the causing most of the runout. I would use a metal or carbon fibre shaft. I wouldn't try and print it. Your sprockets may have a slight warp, but I don't think that's necessarily due to the 3D printing process. It's a basic limitation of using plastic...

Re: ABS printing

It's under-extruding, but you will need to figure out why... 1. Was it okay using this filament recently? has something changed recently? 2. Is this a new filament and/or machine? has it been setup properly 3. Have you printed a simple test cube and checked for overall print quality and dimensional ...

Re: My N1 is stopping mid-print - again

Yes, it is still stopping mid-print. The only way to get it working again is to turn the power off and on. It saves the file and does a good job of carrying on from where it stopped, except that while idle it has usually oozed filament leaving a blob on the print. Can you ask your engineers what wou...

It's the same on both extruders and is the same when trying to print a model. The extruder nozzle was fully primed ...
