Hey everyone,

I finally decided to upgrade my ancient Fireball V90 with a new 4-axis 8060Z machine. I found a lot of material online about the 3020/3040/6040 machines but there was next to nothing...

I have spent the last few days making some videos on basic CNC cutting on a router. They are full fledged tutorials I don't go into every little detail because that would be insanity but its more...

Ok so I whipped up a jig that will allow this to work. I have to do some more work to make sure that the top plate that holds the part is perfectly level otherwise the cut will be thrown off. I will...

I thought about making a jig although making one will be tricky. Since I can't mill at an angle to make a perfect jig I will have to create an angled jig from flat parts.

Recently I added an...

I am trying to make a pulse jet engine with an argus type valve. Below is a picture of one of the reed valve retainers. These are the most complicated parts (geometry wise) in the entire engine.

I'm not trying to take deep passes.


I saw a video online of a gantry style machine cutting a steel plate

If I use a lower feedrate 20ipm and...

Right now I have to make .05in passes through mdf in order to get very good accuracy. The problem with this is that it takes a tremendous amount of time in order to machine the piece. If I set it to...

I have a Fireball V90 with a Bosch colt router on it. So far I've read about people cutting aluminum on it with "good results" but I haven't seen a nice video about it. Right now I've got some free...

I replaced the anti backlash nuts a week ago and the problem persisted. This ruled out backlash. Finally I called probotix and talked to someone about the issue. We went through my setup and almost...

I just finished a fresh install of emc2 and simply configured it through the step config menu.

Below is what I did and how others can fix it in the future if they find this forum post on google.

This sounds like it could really be the problem I have a single port card and the person who wrote the article had a dual port card. I will go and try this in a little bit.

Thanks for the reply!

I decided to get a pci parallel port card so that I could use one of my more powerful computers with emc. The installation went great and when I started up emc nothing happened it ran but whenever...

I was able to get some 99% perfect cuts by looking into emc backlash compensation.

I set the X axis to have .014" backlash compensation and the Y axis to have .011" of compensation after tinkering...

I got my dial indicator yesterday and did a few tests on my spindle.

First I measured the runout inside the hollow spindle of the router.

It came out to be a bit greater than .0005". This is...

I went and ordered a pci card adapter so that I can use one of my beefier computers with mach 3.

I also ordered a dial test indicator w/stand that is accurate to .0005" this way I can test to see...

I had never made flats on the motors so I went ahead and did that today then set the screws on the flats. Right now they are perfect well connected and secured no way there is any movement.

So I...

So I just finished tearing down the X, Y, and Z axis. Everything was cleaned, inspected, and reassembled. The backlash nuts look fine. I compared the X axis nut to the Y axis nut and couldn't tell...

1. I used the step config menu and followed the instructions they had on their website.

FireBall V90 EMC2 Step Conf

My latency test comes out to around 10,000 - 12,000 ns at the absolute max.

I am running a very basic setup with my fireball v90 but a slight problem has hit me and I'm entirely convinced that it is because of emc.

I have a powerful stepper setup with a 40v power supply....

I have a fireball V90 CNC router (w/ bosch colt) and right now I am having a little bit of trouble finding plastics to cut on it.

Just for testing purposes I have been using 3/8in thick LDPE...

Well I fixed problem number two just a second ago ger21's reply got me thinking and I started looking at the meshcam tool path (first photo). I noticed that one of the yellow lines goes all the way...

I am trying to cut 2.5D parts using meshcam and emc2 but I have hit a few minor snags.

First off the cutting time takes FOREVER for a simple part. This is because it is making many passes and I am...

Thanks for the input guys. It turns out that inventor was in fact exporting in centimeters without my knowing.

For anyone having this problem with inventor the solution is very simple.

First...

Today I just finished getting my fireball V90 setup and have done numerous test cuts on it using some emc test files. All was well until I tried to take some simple 3d models and have meshcam make...
