What do you really get for a $350 desk top engraver ?

So i got curious  and took a deep dive into how and why all these  imports are so cheap some things i liked and a lot of stuff i don't like so here i am not able to leave well enough alone.

i wanted to do something simple with linux cnc as a first project to get my feet wet since i have been in limbo for a while with the pandemic turning everything upside down for a while and my kids needing bailed out every time i turn around things seem to be back to normal for the most part now
 The stock machine came with a Grbl controller and Candle software which is beyond basic. the stock table top was MDF and that was the first thing to get replaced. i had some 25mm x 75mm t slot extrusion on the shelf so it found a new home. i thought the 25mm x 75mm extrusion was light at the time and never used it. what is really light is the 3D printer extrusion on this machine and that is getting replaced soon.

Over the last week or so i have been gathering bits and pieces and for the last few days i have been working on the design for a better foundation to build from. here is what i have so far just for visual reference. if i get smart about limit switches and belt tension i actually will pick up over 4" of travel on the Y axis so that is a plus at least should be around 16" x 20 " packed in a 600mm x 600mm foot print.

 

Santa came early this year 4 motors and drives with 2 power supplies plus a 7I96S that came yesterday

on a side note the original machine has the option for a laser so once i get the new frame done for the spindle that's most likely the direction the things will end up going when I'm done with this.
 

Myfordboy did a bit of work on a cheap one a few years ago, not so big but kinda similar project, similar not as involved.

with the exception of the v rollers in the extrusion t slots and the mdf top the machine is well designed. the z axis would be the only linear rails on the original machine. i did circle mill the t slot table i added but took it slow an easy. it did good believe it or not but it took a long time.

this machine came with a 300 watt spindle and runs at 10,000 rpm and is not that bad and was one of the few things i liked. but with the current set up you can not even get close to getting what you can from this spindle.

i don't have any hopes of running it at anything less than wide open so soft material is all i am looking for at high feed rates.right now i would not even try anything more than a 1/8 end mill and a 1/4 is the max with the ER 11 collets.

It sure would be nice to get my open ended belt early it's in the tracking system here. and the estimated delivery date was Jan 4th.

I have 4 days off and plan on doing a bunch and that would just be sweet if that showed up before Christmas

well no belts before Christmas but they did come on the 26th which is way ahead of the Jan 4th date. However they are not steel corded like i thought? i guess i will have to use them and see how well they do? they look like they are well made so time will tell i guess.
