Hi,

How do I go about scaling a dxf file to right size I need, it is currently much too large.
As an example, I know that the holes on it are 1/4" diameter, but measured they are 6.35".

So can i scale the whole drawing based on a measurement of this circle somehow?? I know in other programs I can do this, but have no idea how to in BodCad (v26)

thx

Clamping System for CNC Machine Drilling

February 19, 2019, 3:36 pm

This is my first machine. Its practical application is drilling holes in 1/8" thick aluminum angles along the x-axis.

I'm having trouble figuring out an appropriate clamping system. For now, we have as depicted, clamps with 330lb clamping force on each side of the angles. We have them on the sides, as to avoid interfering with the holes to be drilled along the center of the angle. I'm aware this is rudimentary, and as such, I'm reaching out for help.

If anyone has any advice, it would be greatly appreciated. Upon solving this issue, we are ready to manufacture!

Regards,
Austin Rouse

Mazak TOOLDATA.DAD file format

An incomplete but useful breakdown of the text based tooldata file saved from a mazak QTN lathe. A mill file would have a lot of similarities but also re-assigned letter code use too. Already the case with different turning tools and live tools. An intragrex probably has all the variations... This is probably mainly useful in reviewing old saved setups and comparing to current ones, I wouldn't try to build a tool data file for loading to a machine.
The binary version of the file COULD be decoded as well but that isn't something I have time for now.

New Machine Build AMAT25LV Basically another PM25 clone :)

February 19, 2019, 4:24 pm

Finally made a start.
Enclosure built except for the doors.
PC, control box, steppers all tested.
Machine is torn down ready for parts to be made on the X2.
Going with double nut 1605 all round using AC bearings X,Y and thrust on Z.
Could prob do with a 2005 on the Z tbf.

I've been working on the oil system first while it's in bits. Took out the ball oilers and have threaded their holes to M8x1.0. Have some 4mm push-fit swivel elbows for those and some smaller thread size ones the same for the screws.
Think I'll have to do the Y axis motion before I fit any tubing etc so I don't damage any fittings while the saddle is being tossed around.

The stock design on the Y axis is crap. Table nowhere near centred and it's nut position means it can't go all the way back to the column. To get truly more than 165mm it needs a head spacer and then the table hanging off the front at least 50mm.
Not a fan of that.

The way I'm planning to go about things is to clean up the underside of the saddle and fit the nut further forwards.
Z bellows are being removed and replaced with the roller cover mod attached to the head and the saddle so it moves with both.
When this is all complete the saddle will go all the way back thus achieving a true 185mm with an overhang on the dovetails around 30mm in either direction.

I'll get there eventually and I'll put a pic or 2 up soon.
Enclosure doors will be the last job.

Starting off basic.Steppers running off 36v & 60v.
Using 1600oz/in Z and 425oz/in on the X,Y with Mach3 controlling.

Homing Script Gantry Squaring

February 19, 2019, 1:05 pm

Hey guys I recently overhauled an old MultiCAM router with a new controller and am using Mach3. Everything is set up and running great but Im trying to solve an issue with my auto gantry squaring script while homing.

The issue is that currently X is set up with two steppers at each end of the gantry like a typical setup. When I home X and A home together but only activate off the X switch. Now I went into settings and there is no change if "Home Slave with Master" is selected or not.

However, when I go to Config->Slave Axis and unslave the A axis, restart Mach3, and run the same homing script again it works as intended and A will correct itself to it's own switch squaring the gantry. I then have to re-slave and restart Mach3 again.

I'd like to not have to go through that process and it home without having to mess with the slave axis settings.
I feel like I'm missing something in my script (below). I tried using CoupleSlave commands with no luck (shown in comments in script where). Any help would be appreciated. I have the feeling I need to enable independent A movement somehow.

Also site won't let me upload XML?

Hello Gang!

Just to be sure I get the right thing. I'm looking to power 2 Nema 23 3N.m motors rated at 4.2 amps. I want to run them on 36v. What is a safe wattage PSU to look for.

Most likely coming from Amazon. I know Mean Well is talked about, but I'm not finding that brand in that voltage on there.

Thanks

What Should You Know About Fiber Laser Cutting Machines?

February 19, 2019, 5:47 pm
$

Fiber laser technology has become a new star in laser industry and an emerging leader in sheet metal cutting field. Persistent investment and researches have contributed to prosperous development of fiber laser technology and it has obtained an extensive popularity from modern laser industries. Her let’s learn it from an overall perspective.

Introduction to fiber laser cutting technology:

Fiber laser technology works in the way that a fiber laser beam is focused highly on the surface of materials being cut, in which the laser beam of high energy density transforms into great heat with intensified temperature. Being exposed to such heated and focused laser beam, the surface of materials will melt or vaporize instantly, and meanwhile the gas will be blown into the surface of material to sweep off the residue of powder caused from melting materials.

grizzly G0704 or the Precision Mattews PM-25MV

Hi,
I been researching bench top mills I've narrowed my choices down to the grizzly G0704 or the Precision Matthews PM-25MV. They are very similar mill. Precision Matthews PM-25MV with stand $2037 shipped/ the grizzly with the stand $1702 shipped. What’s important better quality machine I need to less run 1/2 end mill thru alum .05 depth of cut and not struggle, ease of use & getting replacement parts easily if needed, and don’t need the company closed down after I buy it! Each mill has there pros and cons, I do like the belt drive on the PM-25mv (I do plan to do a CNC conversion on the mill later). Cost of converting cnc grizzly G0704 vs. Precision Matthews PM-25MV I don’t know/ it seems there’s a lot more info on the G0704 online
With that said, I'm looking for some input on which mill I should go with based on the features

Please any input would be greatly appreciated!

Hi,

left machine off for 9 days or so, now its forever in the 7 day warm up. It says "KM10 AUX WARMING UP" in the PMC ladder status (at the top of the screen in the PMC ladder). So I looked up all the warming up logic in the ladder (at least I think all of it anways), its looking for M101 to complete, but there isn't any M101 to complete (M101 doesn't do anything)… ideas ? There isn't any mention of M101 I can find in the manual and I've been running the machine since I got it so maybe never got into this state. I also tried just running a few 'warmup' programs for 20-30 mins but this hasn't changed anything.

Thanks

Hey Guys,

Just replaced my servo battery and I am now getting an error every time I turn on my Lathe

PLC Alarm

EX1080 (M7598) X, Y-AXIS NEED ZERO RETURN

Attachment 412787

I can go into the operation panel and set ZERO POINT ADJUSTMENT to "VALID"
I can move all the axis using the thumbwheel, but I cannot ZERO the axis via the front panel buttons

Whats the correct procedure?

The manual says to perform a zero return after an M70 error, but no mention of this above error.

I have tried to follow the procedure to zero the axis via the SYSTEM - NC SYSTEM - MENU - ABS SRV, but the ABS SRV options does not appear after I press MENU.

Attachment 412791

Attachment 412789

When I get into the settings, pressing the MENU button does nothing...

Attachment 412793

I have tried to set the NC WRITE PARAMETERS to "Valid" - no difference

Am i complicating this ?

Is there a zero return procedure via the front panel soft keys??

I have tried pressing the ZER soft key, then each axis, but no movement and no zero return.

Any help appreciated

ESS is big improvement over UC100 - however, spindles starts during boot up?

Good morning all,

I was having all sorts of problems with UC100 having synch errors and disconnects and finally gave up on it. I picked up the ESS Smooth Stepper board from Automation Technologies (it is great having a place where you can go there and pick stuff up within an hour of ordering it!).

I swapped out the boards and got the machine running. The SmoothStepper lives up to its name - definitely a smooth pulse stream!

The only issue I have found thus far is that my spindle starts up before the Mach3 software finishes powering up. This never happened with the UC100.

I know I can leave the spindle off until Mach3 is fully powered, but am looking for a more elegant solution to the problem.

Is there a way to tweak the settings so this doesn't happen?

How to cut Ali side plates for a new CNC ROuter

After owning a chinese 6040 for a few years, I am contemplating building new, bigger, stronger CNC Router using Extrusion.
I want to use Ali 20mm side plates for the gantry, but how do I cut them, cheaply?
I had a silly idea( Do you think this would work?)......Build the new machine out of Extrusion design the plates in CAD. and use the 6040 to cut out all the plates in MDF.
Asemble and use ththe NEW machine to cut all the final Ali plates? ( Is this as silly as it sounds?...lol)

Anyone done this?
Other options?

I don't think I could cut 20 mm ALi plates on my 6040. This is the whole reason for building a new machine.

Only other option is to design and test fit the plates out of MDF and try to find someone to pay to cut them all out?

I'm trying to cut Aluminum Composite Material. I'm using an Onsrud 63-614 bit. It's a small 12"x7.5" mailbox sign I just want to cut out. I called Onsrud and they said do a 12000 RPM and Feed Rate of 54 on the small sign but it just rips the aluminum to pieces, it doesn't cut it clean. I tried 18000RPM and Feed Rate of 85 and 50 with the same results. I don't know how to get it to cut it and look good. I had them all set to a smooth ramp of .25" and I tried them in 1, 2, and 3 passes still no luck. My spindle has a mister. Any help is greatly appreciated.

Thanks
