I would second the Prusa suggestion, you should get a really good ready-to-go printer from them, but for a price compared to the Chinese stuff.

PrusaSlicer is also my favourite slicer, and should include nicely tuned profiles for their own printers.

So, what are the equivalent 32mm (narrow gauge) pearls of wisdom, and rabid generalisations then? Only one really... The shorter the wheelbase the tighter the curve it will negotiate. Of course the tighter the curve the more gauge widening becomes necessary, as well. :dontknow: As philipy says - it...

As far as I know there isn't really that much choice in what PECO do, its just 2 different radii curves, 2 different radii points and a Y-point, that's your lot. Their entire SM-32 range is just 11 items, the list is on their website: https://peco-uk.com/collections/peco/sm-32-32mm Cliff Barker does...

Glad you managed to sort it. I want to get into resin printing this year - built a new shed last year so I can get one without stinking up the house with resin and alcohol. I enjoyed toying with my filament printer over the past few years, now its probably tuned within an inch of its life, pretty re...

Well, that at least rules out problems with the slicer or model, it seems the machine can't reproduce what is being asked of it. I don't have any experience with resin printers, so I can't be of much use on that front. I know some printers peel each layer off the resin vat film, I wonder if some of ...

Do you have some way to view the individual layers the slicer is creating? Maybe run the print without resin and see if the LCD mask shows the correct bolt pattern at the right time in the print? If the LCD is showing the the bolts, you know its some kind of printing problem, if the mask is also mis...

Simon How would you go about something like this? I can't even think of where to start, even in Tinkercad :( I have had success with your domes and flares. I can now print any dome I like with minimal changes, I can't thank you enough for that :thumbup: Untitled.jpg I've had a bit of a go a that on...

or there is a control wheel in front of his right knee. I thought it might be a handbrake wheel, but there is no evidence of brake shoes on either version....... :shock: I noticed that too, I was wondering if that handwheel screwed the block of wood directly underneath it down onto the track to act...

I've abandoned prints where the filament has run out previously, as I didn't think it's be possible to change successfully. Yes, I can confirm that it is possble to change filament in mid print although you do need to get the 2nd filament all ready, you only have a few seconds to feed it in. Must a...

Good to see the results of your experiment, I think I'm in agreement with Philipy regarding the usefulness of PETG for models. I do have a roll of it, but haven't really had a good reason to use it yet. Regarding the stringing, I've seen that excessive stringing can be a result of the filament takin...

I moved from M5 rods (0.8mm/rev) to TR8x8 leadscrew (8mm/rev) which meant I had to change the steps per mm. Steps per mm should not really be a calibration per se, the correct value can be calculated by knowing various physical aspects of the machine, including the steps per revolution of the steppe...

Looks like typical z-banding or z-wobble artefacts, if you look up those terms online you will see a wealth of information on this common issue. You say its every "1mm or so." Coarse M8 is a 1.25mm pitch, if the banding lines up with the pitch of the leadscrew you know its something linked...

Fusion 360 is free for personal or hobby use. It has some restrictions, like you can only have 10 open documents at a time, but if you do an entire model in one document that's not an issue. The FAQ says "A hobbyist user must generate less than $1,000 USD in annual revenue, using Fusion 360 for...

Biodegradability is not something you have to worry about regarding PLA prints. Its only really biodegradable in industrial composting plants at high temperatures. PETG has better heat resistance than PLA, which might be helpful for model that is a dark colour and gets direct sun so it heats up sign...

If I remember correctly the Big Big chassis are originally a 2 series 2 parallel arrangement, but of the much larger D or C cells, resulting in 3V total. As Steve said above, the parallel arrangement gives about double run time versus just the 2 cells in series.

If you are a member of the 16mm Association, you can download issues of 16mm Today back to 1985, perhaps in a flick through some of those you will find something you really like? There's also the index, where you can look at a list of drawings from 16mm Today and get a link to the issue that include...

If the worm wheels are standard size, then maybe a motor with smaller diameter worms might give more thrust. I'm hoping that assumption is valid. With worm gears, the gear ratio is dependent on the number of starts of the screw, not the diameter of the worm. E.g. a single start worm used with a 40 ...

Hi. I am not sure if you found that video or made it fort his example? However it took me hours to follow that video and I still ended up doing things a little differently as I could not see how some of the things were done, presumably keyboard shortcuts? Yes, I definitely used keyboard shortcuts i...

Out of interest I have just had a go with TinkerCAD, your results look brilliant for what a basic set of tools it gives you. I haven't seen a good way to do the flare on the dome in TinkerCAD. This is how I would do it in Fusion 360, its very easy, at least when you know how to do it. :lol: https://...

Is there a way to view the slicer's output, layer by layer? If the odd face issues are visible in the sliced output, you know it's a slicer settings problem, otherwise you would know it's some problem with the printer not producing what the slicer software is expecting.
