Hard drive crashed. Reinstalled Mach4 and upon loading any of the basic profiles, I get this message. “Could not initialize the core instance 0! rc = -17“ anybody have any suggestions? Thank you, Chuck.

NEW Steel 5axis CNC 3040 machine
14
Hello, I am now the owner of this 5 axis mill from Chinacnczone Store. I was initially going to get it with MACH3, the shop persuaded me to purchase it with Easycnc as a alternative controller software. This has been a retrograde purchase and I am looking to change to Mach3 which I have used for years. The issue is that I cannot get any technical, configuration info on this controller. Has anyone beeen here? The existing I/O box is a genuine B "Black Box" it is black, works, no manufacturers or Part number identification. In fairness it does work. But I wish to add control relays and have no info as how to, or configure the logic/PLC type control. Has anyone been here before?? Regards Graham

Product copying issues: I have at least three cases of my products that were copied: 50 years ago, I designed a police scanner radio that got popular. A US company copied it and “improved” the high frequency RF section to make the PCB layout “cleaner”. They did not understand that the strange layout was intentional. They never made it to the market. 30 years ago, I designed a money changer: A dollar bill input, and 3 quarters, 2 dimes and a nickel were dispensed. The coin dispenser section sheetmetal had an unused accidental hole. A US company copied it correctly, including the accidental hole, and marketed it. A few years later I was inspecting a company in China and their engineering department was busy copying the copy, also including the hole. What a coincidence! There are zillions of companies in China, and I happened to evaluate that one. 25 years ago I designed an RF transmitter with a digital memory to transmit recorded information on the FM broadcast band. Again, a US company “improved and cleaned up” the RF section. They never could get it to work properly. Bertho

n the attached pic, there is an oil grove that starts at the end, goes in roughly an inch in 270 degrees and then backs out in 270 degrees. In the pic you can't see the exit, but is 180 degrees from the entrance. I could write a threading G-code, or use a canned Mach4 threading program to do the inbound groove and then do a second program to do the outbound. But how would one "connect" the grooves together? How does Mach determine at what point in the circumference to start? Another option would be an inbound G-code followed by an outbound G-code. Then move the tool in the X direction. then do the same in and out G-code. But would the tool start at the same spot like threading? Thanks for any insight. I guess I need to go experiment.

Is anybody using EtherCAT?
4
After seeing a LinuxCNC video on EtherCAT last year, it intrigued me enough to purchase a set of EtherCAT closed loop steppers, and a couple Beckhoff modules to do some testing, as I like the idea of simpler wiring. However after going through three different setups (RPi 4, older mini-ITX mobo out my mill, and an Odroid H3+), all it resulted in was realising LinuxCNC has various issues, and a flaw in the EtherCAT stack whereby the first drive wouldn't initialise unless you started the master before plugging in the Cat cable. The EtherCAT drives have since been sat on my testing bench while I weigh up options. Now I've seen the This Old Tony vid where he installs the Automation Technology/IntervalZero/Kingstar setup, but they only sell that as a complete turnkey system, so by the time it gets shipped over the pond, it works out quite expensive. I would have been interested if they were to do this as a software only option, but that doesn't appear to be an option. The other option I'm aware of is the Vital EC01, however I can't seem to find anybody who's actually used that system. So is there anybody who has an EtherCAT setup running Mach? If so, what setup are you using, and would you recommend it? At the moment, I've got a router planned, which I'd be willing to spend the extra on EtherCAT servos for, but I want a reliable test setup before committing to that. Thanks

I'd like to wind a few coils. I seem to remember that there used to be an add-on (or some such) to wind coils using Mach3. Is there a repository for all things coil winder? Where I can get an idea what is involved?

I have acquired and Boxford Duet Mill unsure if is a mark I or II, see pictures. The original software is Dos based really want to move onto XP or Windows 7, i am hoping to convert to Mach3 control. Any suggestions welcome, has any member done this? I have no problem with wiring or PC operation, being a electronic/electrical engineer, I am looking for advise on the best solution and control cards to: 1. PC interface Card 2. XYZ stepper motor controller card (Hopefully can use the original stepper motors) 3. I need to control the Lathe motor speed from Mach3 4. Limit stops I have from a previous project, would any of the below be suitable? DollaTek 5 axis CNC Breakout Board with optical coupler For Stepper Motor Driver MACH3 Mach3 Motion Card, CNC USB Card Distribution Board CNC USB Motion Control Card Mach3 4 Axis 100KHz for CNC Engravingraspberry pi CNC Controller Padarsey DC 24V 15A 360W Power Supply. 3 x Dealikee TB6600 4A 9-42V Stepper Motor Driver CNC Controller Nema 17/23 Stepper Motor Single Axes Two Phase Hybrid Stepper Moto

How can a DXF file be converted to a G-Code file?? My computer hard drive crashed and I lost a lot of data. I thought I had backup files of everything, but I had a bad disc and lost some files and apps. I installed DXF to G-Code Converter but it has a glitch and does not work. I could use the CAD file and spend hours writing the line code, but that is too time consuming. I would appreciate the info to convert DXF to G-Code.

I may have to pull out the scope but I'm having trouble with the PWM output from MACH3 to a USB Smooth Stepper. I have the Spindle set in Motor Outputs to pin 14 Port 1 and Direction set to Pin 16 Port 1. Under the Spindle Setup I have Use Spindle Motor Output and Use PWM control. I have the Motor Spindle Relays disabled. The USB Smooth Stepper is plugged into a PMDX-125 BoB. There is an LED on pin 14 and pin 16. When I have the Spindle configured to use relays and switch on the spindle the Pin14 LED comes on. If I have the spindle configured to not use relays and instead do the PWM at 100% PWM or full speed I should see the LED pretty well full on. And here's the issue I think I'm having. How does the system know what full speed is? Which parameter is that? Ie. If I do a Gcode S1000 M5 I see the spindle activity button blink and I see 1000 RPM in the speed set info on the main screen. But no LED ON at pin 14. So how does MACH3 know that 100% is the same as say 1000 RPM? Thanks John

MACH4 and Lathe Spindle encoder

Can MACH4 Lathe still work with only a 1PPR spindle sensor or does it now require a full quadrature encoder and Index pulse?

Gecko G540
3
I realize this isn't completely a MACH question but many MACH users have G540's connected to their systems. The VFD pins are the ones I'm wondering about. The specs say optically isolated PWM. Is this as simple as an opto-isolator on Pin14 of the DB-25 and a capacitor connected to the output transistor to create the DC from a PWM output? Instead of 10V (Max 12V according to the data sheet) to the VFD-10V input POS9 on the terminal strip if instead 5V was connected would an end user see 0-5V voltage for 0 to 100% PWM? For connection to a DC motor spindle driver. Thanks John

Hi, Trying to move my Mach3/Ess from Win XP to Win10, I get an "Error triggered" "Art Code 1" and "Art Code 9991" at the startup. If I create a new profile by cloning my working profile, everything works fine the first start (even the Modbus logic) but the second time I get the error again. If I uncheck "Modbus InputOutput Support" before Exiting evrything works as normal the next Start. I reinstalled everything from scratch but still the same, seems to be a Modbus/Win10 problem... Mach version is : 3.043.062 Any idea ? Thanks. Chris

Mach3 Tool Wear Compensation
2
I understand that there is a tool wear compensation available in Mach3 but the only place I can find anything associated with this concept is on the tool table where it say Diam. wear. I am using Fusion 360 to generate G-code under compensation Type there is a wear option. I would like to be able to use this when doing final cuts for bearing bores. I don't understand how to implement this in Mach3 I have read there is a Tool control tab in Mach 3 but I have yet to fine it. Please advise

Rhino3D, Meshcam and Mach3
3
Hi Let me ask a quick question without doing my due diligence or research before hand I'm currently working with Rhino3D, RhinoCAM Mill, and Mach3 on a home made CNC. I've heard good things about meshCAM from other violin makers and a thinking of giving it a try (since RhinoCAM is getting a bit pricey). I was looking around for Mach3 post processors for MeshCAM and am not turning up anything that jumps out at me and says "here it is". The meshCAM site says comparable with Mach3. Does this mean they have a Mach3 post is supplied in their software? Anyone have any feeling for how well meshCAM works with Mach3? Thanks Steven

Where are the Mach4 screen sets?
11
The YouTube Mach4 demo: https://www.youtube.com/watch?v=35AefYpXy_0 Shows many included Mac4 screen sets. The download and the website only show three. The search function appears to be broken for Mach4. I found a link to lots of Mac3 screens. Where are all the Mach4 screen? Take Care, Stay Well & Safe, Bertho

I've recently purchased a 5axis HY6040 desktop milling machine. Mach3 came with the machine. After installing, and opening, the Mach3 software the app it is missing much of the graphics. I tried to install everything according to the user manual for the machine; although, the installation instructions are not entirely clear. Anyone in this group purchase and set up one of these machines? It appears that the driver isn't installed. I've uninstalled Mach3 and installed it twice now and It doesn't seem to install the driver. Gerry
