What a wise man!!

Yeah, I have to stop that, it hurts the brain!!!
The problem is "you were thinking" again.

I was thinking about 3D printing something but thought a metal 'box' might be more constant and wear less.

there I was thinking I had come up with a new inovative idea!!!
here what I plan to do is have a 'Z axis block' and use this to set the end of the bit hight. Place the bit lousely in the spindle, hold the bit up with the 'block' and tighten the bit in the spindle.

I would like to add, this just a block, no probe involved. I don't think my cheap and basic controller card can use a standard touch probe so this idea of a block (adjustable in hight??) To just set the bit hight is easier to work with and avoids messing around with changes to the z zeroing in the cam cad software.
So the idea would be to zero the X/Y with the endstops, install the bit in the spindle with said block holding up the bit at a specific height, then tightening the bit in the spindle, remove the block and you have zeroed all the axis. For tool change, go to home, remove the bit, install the next bit, held up by the block and tighten the bit, remove the block and off you go!
Seems like it should work....

Hi guys,
An idea poped into my head..and it sounds like a good idea but maybe I am missing something and you can set me straight...
So in order to get constant z axis bit hight I thought to use a metal block of a specific hight. The top  of this block would be the z axis zero. This would allow constant zeroing of the bit on tool changes.
As long as the top of this block is higher than the top of the material (and you don't rise the z axis higher than physically possible in your gcode then I can't see why this wouldn't work.
The X/Y axis have endstops so no need for a touch probe.
All of this came about from me wanting to run roughing passes and therefore needing tool bit changes. I needed to find a way to keep the z axis bit zero constant and this idea felt like is solved this issue.
I have a mate with a cheap 3018 CNC and this could work for him also...?
Maybe it is not a new idea but it is to me!!!

Great to hear from you guys and that you are still keeping yourselves busy (and there fore theoreticaly out of trouble!!).
I emptied the water out of the tube and filled it up again, making sure there were no air bubbles in it but yeah, I think it might be time for a new tube. I saw someone adding a drain pipe to extent the tube out the side to allow for a bigger tube (and therefore a more powerful one. Seems like a good idea to get a 60W instead of a 40W but I have other things to work on (a cnc I am getting working) so I will probably just get a 40W.
As far as purchases go I did not buy anything new except the house!!! So I am broke but can now make as many holes in the walls as I like!! WOOT! I also got a dog so I have been busy!!
As for the laser tube do you guys have any recomendations as to where to get one? My usual port of call would be ebay...
Off to listen to some more 'lofi'!!!!
Take care

Hi guys,
Its been a very long time (far too long, I was away for several reasons but things are looking up) and I now have the strength and time to get back into lasering and get my diy cnc going. In looking for inspiration I found this, 'cnc lofi'. I listen to lofi tunes on spotify as easy listening but found it funny that there is a 'cnc' version.
I will update with any progress I make but right now outside of work I am concentrating more on the cnc than the laser (the Co2 laser seems to have lost its power, hope I dont need a new tube)
Enjoy, I hope all is good with you all.

Tahnks for the advice, looks like I just have to train and train and train. I did not want to use those choking collars so
I will see how it goes.
I swear, after posting here the puppy started to noticably behave, especially on a very short leash. He stayed close without pulling.
It was really great as when we passed a school he resisted going to play with the kids. That is huge progress.

I will keep at it, thanks again for the advice


I hope you are all doing well in these complicated times.
Having recently taken up the challenge of owning a dog, I was wondering if users here could suggest a good dog forum. I ask as I have a few questions I would like to ask. For ex; my 15Kg+ puppy pulls a lot on the leash. I am trying to train this out of him but progress has been painfully slow, he keeps ripping my arm off. I was wondering if just to get the training to stick, so for a short term, one of those choke collars might be useful. Personally I detest the idea but I need to think of the dogs training because as it stands my daughters get pulled around by the pup and this has led to cuts and bruises.
I have other questions so this is why I am looking for a correct dog forum.
I dont know if it matters but the dog is a Bouvier Des Ardennes, forums for this breed would be cool, I looked but could not find any..
as posts without pictures are useless here is a picture of my new copilot!
I have read into it and I am no convinced about these choke collars. I will look into some other training.

yes, indeed... especially if the laser still engraves slate no. 7,8 etc and the issue is only with no.6!

General Discussion / Re: CNC 'wood'router to ER11 collet?
« on: April 03, 2020, 02:20:14 AM »
My fixture?
The machine I have you mean? It is a 60x60x7 Cm sized metal framed machine, Mach3. The spindle is a woodworking no brand router..
I am planning to make an adapter for a chinese 5700rpms spindle I got last year..this have an er11 spindle...
So for the moment I can only use woodworking router bits, they are not fine or small as I would like but will allow me to learn and get started...

Hi ggallant,
Then thats a shame but not the end of the world.. I will look for new bits for the router I have.
I saw on banggood that there is an adapter shaft type of thing... I might also give that a go.
Thanks for the reply

Hi ggallant,
I do a lot of slate as it is smokeless and have only had something similar with different sources of slate..
I would suspect some sort of coating... you might try sand an edge of this no.6 slate and try laser on the sanded area to see if there is some sort of varnish on it..?

General Discussion / CNC 'wood'router to ER11 collet?
« on: April 02, 2020, 02:03:58 AM »
Hello everyone,
I am so very happy to report that the renovations are nearly finished and I can finally start to re-organise my 'workshop' room... so many plans..
So, in order to get going with my 'new' (2nd hand) cnc machine I would like to know if the following is even possible and if so what parts I would need (and what they would be called) to be able to use an ER11 collet system in a normal woodworking router as is already installed on the cnc.
Is there a name for the nut thing size on an standard woodworking router (1/4 inch???) and a name / size for the new one I would need? Are these things even called router nuts?
I have got a new spindle for ER11 collets but need to build and adapter and that wont be for a while...
Thanks in advance for any help, it is appreciated as I cant wait to get going on this cnc, sooo many projects (think star wars Inca calendar!!)
