I've Gone and Done Something Mental

[mtt.tr]

A SHORT while???

Better not watch her with a Creality CR-5

Seems kinda desperate

Oh god not something else

I don’t use cura but you could try ‘Spiralize Outer Contour’ this then prints one wall thickness. It may not be suitable as you can then only print one object at a time and I’m not sure if it can be turned on at a specific layer height.

When I printed drill guides for a 6mm bit, i found the hole printed just a tiny bit too small too.
Part of it is caused by elephants foot, where the first layers get squished. The other part is STL files are just a bunch of straight lines, if you dont play with the output settings, round things can look more hexaganol.

Anyway, I just ran the drill bit through it to cut the hole

I have found it easier to tweak the model whenever I need something to "fit" another item, and then do a test print a few mm high to prove. Far easier than trying to alter printer settings to achieve a result.

I have ordered five 0.2mm nozzles to play with. They were a more sensible buy in a pack (£1.11 each) than individually (£2.77 each), so if anyone else wants one, talk to me.

Little repair job for a customer. Plastic holding tab broken off, so a new tag designed, printed and fitted.

*Dear ajlelectronics,*

Hi

Thanks for your order but I'm forced to issue a refund having recently being
diagnosed with covid19 - I can only apologise

I am in the middle of upgrading my printer. The dual Z kit had a faulty harness so have just sorted that, the socket was wired mirror image so the unit tried to home skywards. The socket works like the DuPont connectors in that you can lift a plastic tab to withdraw the connectors. Rewired, it does as it ought.

The issue I have is with the BL Touch device. I have put in the latest firmware off the Creality site, but now auto home does nothing. The servos do not run in any plane. Putting the original firmware on allows it to work again in standard configuration with its limit switch connected. I have checked and double checked but cannot work out what is going on.

Edit. There are two lots of firmware, identical bar the version number. I was using the latest 4.2.7 which didn't work. However the 4.2.2 version is actually doing something.

Edit 2:

I have it working. The auto home puts the print head in the middle of the bed and about half an inch high. Attempting to print lowers the head but nowhere near enough. It seems that you have to "Tune" it by putting in a minus offset for the Z axis. I have used -3.50 and am printing a calibration cat without 3DLAC and it seems to be sticking for the first time. Strange.

For finding the offset, I had a tall and narrow cylinder shape ( a car door interior lock button) printing without filament. The Z axis can be adjusted on the fly, so it was a matter of putting the .082 feeler gauge under the nozzle as it thought it was printing and bringing down the Z axis offset bit by bit. NONE of this is in the instructions for the BL Touch.

Edit 3:

I have noticed that the fan underneath the motherboard doesn't run. Is that thermostatic or faulty? Perhaps someone else with an Ender 3 V2 can see if their fan runs. Mine is all properly plugged in.

The fan has just started so seems to be thermostatic.

Just designed a support / repair bracket for my cat fencing, due to 'indoors doing Tarzan impressions on it...

 

[ajlelectronics]

Door number for the new gate.

 

[ajlelectronics]

Upgrades all sorted now. BL Touch and twin Z axis drive. I have done another couple of prints and they adhered correctly without the lacquer. All very strange as the .082 nozzle clearance is still the same as it was.

I haven't tried the 0.2 nozzles as yet.

 

[ChrisBailey]

Is the BLtouch worth it?
Ive not had anything loose adhesion yet.

I was finding that the bed level kept changing, despite careful analysis of the structure and using locknuts on the wheels. I have fitted the new springs to the bed which has raised it up well clear of the reverse servo too. I can't explain the adhesion issue, nozzle clearance wise there is no change. Also I have noticed that the support bed and the glass plate are not totally flush either so the BL Touch is a bit of belt 'n' braces.

I have an Ender 3 v2. Usually when I get a new toy I take it apart, modify it etc. For the first time ever I have just plugged it in, switched it on, levelled the bed and started printing. And it works a treat.

If I only I could design things. I just cannot get to grips with Fusion (gone now anyway). I tried the RS Components program, no luck at all. I needed a hole in the object. Looked at a tutorial, 'use the drill pad'. Easy, where the hell is it?
Which CAD programs do you use?

Try Tinkercad, That is easier to use apparently. I'm trying Freecad but it's probably harder than Fusion but the interface doesn't change every time you use it

With DSM, to make a hole is very easy. Draw a circle of the size and position required. Select it and click PULL. Move the mouse and pull the circle through the workpiece like a cutter.

What can you achieve so far in the program? I can take you through the bits that I have learned. The tutorials are not wonderful and only "video" tutorials are available apart from the "press F1" help. When I was struggling with parts merging unwanted, I found the forum to have some very helpful people on it. My next challenge is screw threads!

Hello, as usual I am over-thinking the problem. I thought it would go like Fusion and create a column above the piece.
I shall persevere and get back to you.
The petrol hose turned up next day, thanks

Jolly good. If you wish, I can spend an hour or so with you one evening over a video link or whatever? I am very far from being a DSM expert but I can make simple geometric stuff and have recently worked out how to apply text.

Pull works in various ways, it can thicken a piece, enlarge it or cut something. Using it to increase wall thickness irritates me because it defaults to "move the whole wall" unless a toggle is pressed every time.
