I did a modified high Z with a sheet of .75 mdf as the base spoilboard along with strips of .75 mdf and T-Tracks. I'll get a picture, my explanation is bad.

 

I think I understand what you did, I've seen some similar things on larger machines - so you are losing 1" of Z total between the. 75" base spoiler board vs the .5" they use, and another. 75" with an upper layer with t track in between strips, correct? Was the modified high Z an option on the machine you chose? Like with a taller gantry? How are you mounting the strips in between the t track to the spoiler board beneath?

 

There are t-nuts on the bottom base so I can just mount new strips of spoilboard from the top. I did have to move the furthest outside braces inwards about .25 so a full sheet would fit but it was worth it. I took the high Z mounts and cut them to 15". Gives about an 1" more than stock when it's all said and done.

 

I ordered the high Z mod but cut it slightly shorter, so I gained additional Z. The full z mod was too high for me.

 

Very interesting Rhett. I was just thinking about T nuts on the underside, but was trying to figure out how I would mount them. I really like your setup!

 

Can this design handle a water cooled spindle? 2.5kw? I am just a week old in the CNC world and I am buying this one piece at a time.
So while I am buying parts I am focused on spindle vs router, software, controls, motors. Any help would be greatly appreciated. You can email me as well [email protected]

thanks guys!!

 

I just watched a video on YouTube that a young guy saying that there was a plasma cutter kit in the works from open builds. Has anyone seen anything like that? It looked very much like this machine

 

Hello, so I received my 1515 last Friday, built a bench Saturday, unboxed the beast Sunday and laid everything out on the bench and started my build. Most of Sunday and Monday was spent pausing, rewinding and fast forwarding the build videos which I must say can use a bit of tweaking to maybe show what the part should look like once connected as well as better lighting when highlighting a spot on a black piece of aluminum. Also dump the part about feeding the wires through the guide chain and add the one were the chain is popped open and the wires are lid in...what a headache that was...only to find out the router still had to be fed through it...

Either way I managed to tweak everything including the c beam after it misaligned because the video said, "well tighten those later"..lol

Now I am at the hello world first cut and I continue to get an error about cut larger than machine area so I check the grbl settings and apparently the maximum x y and z seem to be for a smaller machine?

 

Will this be offered in a 1510 size (60x40)?

 

I'll save you a migraine for later. Take that router power cable back out of that drag chain. You'll get all kinds of EMI, or at least I did. OB did the same in later videos.

 

To prevent just that I used on my spindle a shielded cable with metal mesh that I grounded on the supply side only! I have the cable running in the drag chain with no problems.

Unfortunately I had to buy that wire in China since I couldn't find it here in Canada. I couldn't believe that the electrical wholesaler didn't have that available.

 

Thank you! interesting, i see they may have added an emi filter to the power line, mine has one but if i start having issues i can add another 20x20 and run a separate chain. right now i have a $3,000 paper weight...lol

 

it stops here, after z move up 5.06mm and triggers the limit switch even though it has just been homed.

i have also for some reason have had to select invert X Y and Z directions even though i have gone over the wiring 10 times and verified my color combos are correct

 

when i run job i hear the blackbox click and then get the message, can't be emi as i have not even plugged the router in for the first time, blackbox sounds like a relay clicking. then error. so it seems like it is simply going through the code and saying nope, settings are going to cause an issue. now if i run check job, it draws a square with no issue

 

homed and set zero even though they all came back to zero, if someone wan't to call me it might be easier and if these systems are so vulnerable to emi would it be possible to use cat 5 or 6 ethernet since it is already shielded?

 

oh i had done this day before yesterday same issue, just did it again to verify and same issue.

does it matter how far the limit switch is? the one for the X axis is about 4 inches from the spindle

 

impossible yes but here is the code

yes i went according to the video..

 

but Peter, this is the hello World pop the CNC cherry job created by openbuilds, not mine...lol i did it step by step from the video, download Control software, select your system, pull down hello world, run job. did i miss a step where i had to make additional changes to the profile i pulled down?

 

i turned off BOTH hard and soft limits and now the job did in fact run but now i have a broken limit switch... guess i have to take the good with the bad.

 

I can't help but laugh out loud at this, There is No stock, There is NO wasteboard, hell the router is not even plugged in, i don't even have bits installed...LOL
