beginning to get the hang of this
« on: April 07, 2018, 06:51:05 AM »
Hi,
I am beginning to understand what is happening now with this laser engraving (could have been last weeks holiday up Glen Clova without phone contact)
Finally have what I want, where I want. Happy with this image for the coasters. The square outline was just to confirm what I wanted.

You have some significant backlash, which shows up as that saw tooth pattern.

To show you the difference disable bi-directional mode in the settings / image options menu.

Thanks for that Zax. I have tightened the belts and have disabled bi-directional mode with these results.
The right hand pic is the original, the centre pic is after the belts were tightened a little, and the left most pic is when I disabled bi-directional mode.

I would say the issue is fixed, your results are looking good. You should enable bi-directional mode as it's significantly faster.

you might want to check your wheel tension.  it can cause backlash too.  it looks like your middle one is better but it is still occurring.   https://youtu.be/ZzO9skEYqwY?t=55s

Thanks guys,
@Zax, It is getting better every time I use the programme. I just don't get a lot of time to do any work with it.
@nottingham82, very interesting video indeed. Can these these upgrades be purchased in the UK ?? I am looking to buy a 3d printer but it may be some time away.

The file is free online. There are services which you can pay to print it for you. Like 3dhubs or shapeways or print a thing.

Duuuhhh. What a wally. I am so sorry about that nottingham82, I didn't realise you are the man responsible for these modifications. They are so great.
I have made arrangements to visit a local 'Mens Shed' that has a 3d printer and hope to get some tuition on operating a printer before purchasing it. I will ask if they will print these objects out for me.
My main problem with buying a 3d printer is finding a stockist in the UK for the parts etc. like new Delrin wheels. Everything I have seen seems to be located in US of A. Hopefully someone here can put me right.

Nottingham is also responsible for a couple of excessive compulsive laser etching projects around this corner of the universe. There are simple 3D printable adjustable belt tensioners available.

Thanks for that ggallant571. I am being blown away with the wealth of talent here. You don't really need to go anywhere else.
Everyone is very helpful and very free with their experiences, this is a simply super site and I am glad to be a member.
Many thanks to Ralph for hosting and keeping control of the site and to Zax for his comments you are all great.

take care
Don W
PS I may be buying a 3d printer this week which will mean I need more help than ever  ;)

It's a natural progression. 2.5W laser etcher => 3d printer  => 40W CO2 cutter => CNC mill => divorce court.

To be frank I would like a mill but a manual, possibly Bridgeport with electronic axes. I am a throwback to the (good) old days.

Will get the mill before the CO2 but maybe not before the divorce court. The printer is almost taking care of that. I need to print more stuff for her
