Quick question has this ever been sorted? I am having the same issues, its not technically inverted, but going from LaserCAD which shows everything in the bottom Right X0 Y0, to my laser the origin...

I absolutely love this! I found it on youtube, it made my day and I really cant wait to upgrade my machine now!

Thanks man! I have a 3 year old CNC Router Parts PRO4824 and I do a lot of parts that are acrylic and delrin but i am also running a couple aluminum parts that are starting to sell well, but the rack...

Anything ever happen with this CNC build, been hunting for dual drive Z axis machines all morning this is the first I found, I wanted to build something that is like super rigid but highly accurate...

Lol yeah sleeving can become quite tedious, thats why presleeved cable extensions have become quite popular because you just clip them on and you just hide your ugly wires behind shrouds while only...

Small holes are for aesthetics basically, but allow the option to run fiber optics to light up the cables.

Yeah ideally I would use a YAG laser to cut these parts and then make a fixture on the CNC to chamfer the holes. I don't have access to a YAG laser and we already are maxed on budget so we cant make...

- Yeah the DC kit looks sweet, that is what I will most likely run with, also I figure I could grab that and if I still need more power I can upgrade to AC later when I can afford a quality...

Roger- I was looking at the Motors on AutomationTechnologiesInc.com : Either this DC kit for 1500$ http://bit.ly/1STC7ro : Or I might build my own setup using one of these AC servo option, AC is a...

Leeway - Oh I see now, You have the new bearing tension setup, it does look much better than the sleds, I sent Ahren a message on their website, I will probably make the upgrade.

Roger - My goal...

Roger- Haha yeah I understand bud, Im just hoping these production jobs I just landed will save me from poverty and pay for these upgrades, I went into detail in my previous comments but I have the...

Rcaffin - I totally agree, this machine really got me through a lot of work, its a solid workhorse. The way I look at it is if I need tighter tolerances I'm heading in the right direction, I just...

Ahren - Well it seems my issue is the bars not being parallel, I measured their distance in 5 spots and had a runout of almost 20 thousandths, I am going through my clamps right now and trying to...

The lift off the rail is when I twist the Z axis side to side on hand on the spindle one hand on the motor up top, each side lifts bout 15 to 20 thousandths.

I have the sled at the bottom torqued...

Anyone have any idea how to get this carriage clamped down tighter on the rails?

@Ahren Am I missing something or is this something common?

Hey Ger Thanks for the reply!

I am running one aspire file, and 2 seperate G-Codes. One inside profile path with a .125" single flute end mill to cut the larger holes and a drill path for the...

Thanks guys!

Leeway, Rcaffin - Thanks for the ideas and tips! Going to run a spotting path now to see how those holes line up.

Ger - I know the circles aren't perfectly round but damn they...

Thanks for the quick feedback everyone!

Ahren - yeah my machine was built just before you released the new gantry supports. Im designing my own cnc currently and plan on building another one so it...

Hey again guys, well I squared up my gantry and the machine is cutting great, but something is still off in terms of accuracy. The plastic parts from before in my video are cutting evenly now but...

Thanks Ahren for all the information. I ran a test after squaring my gantry and viola! it cut straight and then after the cut i brought it 1 inch from the ends and it was still square. I will take...

Also on my X and Y axis, The velocity is 199.98 and the acceleration is 15 and the Gs are0.0388528 Step Pulse is 2 and DIR pulse is 2.

Also I ran the Mach3 calibration, I did it over 20 inches for...

Okay so I found what I think might be the problem. I backed the left and right gantry support plate 1 inch from the sensor bracket on each side. Put a framing square up to the gantry itself on the...

Thanks for the response Ger. Sorry for the shaky video, I was excited/annoyed at the point I filmed it. Most of the information needed is in my commentary, at least the explanation of whats going on....

The video is fixed! I will shoot you an email directly with the link to the video also Ahren

So sorry I posted the wrong link, Im fixing it now. I just wanted to get as much input as possible. I havent had issues like this before. The machine has been really excellent since I built it but...

Hey there guys, here is a video I made to explain the problem I am having. I need to try and fix this asap and this issue has been ongoing since my last post about my mach3 crashing the XML file....

Im primarily cutting acrylic and aluminum. Seems to be cutting dead on now Im cutting convention with a .005 offset and it dead nuts. Now my final question, in Hoss's calibration youtube video, he...

I found the issue I think, a bolt was backed out on the Z-axis carriage, and it was tweaking the carriage each time I tried to calc the steps so it was off every time I set it. I torqued the bolt...

Okay, I have never seen issues like this yet. My XML file corrupted somehow, I had to reformat my CNC PC and reinstall MACH3.

I have the old nema 23 3/8" low inductance motors and a G540 driver. ...

Thanks Ahren! Actually I was very close to waiting for the newer model gantry risers but I wanted to keep building so I didn't. I saw the new one but to be honest it will be much more fun making my...
