Mach4 General Discussion / Re: Retrofit masterwood Y coordinates problem

« on: August 14, 2019, 01:54:53 PM »

Thank you people for the replies. Today I tried to mill the rectangles in two times. So first the upper part and second the lower part. The upper part was perfect but the lower part was 5mm to low. This explains why smaller parts would be perfect because those would be milled in the upper part of the machine.

The problem was an faulty encoder. I switched the x axis and y axis one and the problem transferred with the encoder.  I purchased the encoders 2 months ago from a supplier. But the one on the y axis was faulty from factory and skipped pulses when the machine would move fast and far.  This is why the slot would mill great because the entry point was close to the home position.

Thanks for the replies, but the problem is solved.

kind regards,
Jelle

If the dimensions machined are accurate it sounds like you are not locating in the part accurately. Shift your Y work offset by the amount it is off.

I agree that it sounds like  that. But I use g54 everytime because my machine has pins to always locate the part at the same location. So the location is always the same. The strangest thing is that when I use the slot operation from fusion360 the dimensions are perfect, but when I use the 2D pocket clearing/adaptive clearing or the 3D pocket clearing/adaptive with the same work offset. The problem occurs.  So it looks like it shifts the y coordinates when I use those operations.

I think it is a very strange problem. Thanks for the response.

Kind regards,
Jelle

Mach4 General Discussion / Retrofit masterwood Y coordinates problem

« on: August 13, 2019, 04:15:59 AM »

Dear people,

I am retrofitting an old masterwood project 309 with mach4 and a CSMIO-ip/a. I am at the stage that I can test the machine. I now havea porblem with milling somehting. I use fusion360 to generate the gcode. Below you can see a screenshot of my sketch. The problem I have is that the upper y value between stock edge and the inner rectangle is 100.5mm and the lower value between the edge and rectangle is 99.5. The distance between the inneredges of the rectangle are perfect. It looks like the program takes the whole  rectangle and places is 0,5mm lower on the y axis. The stock dimensions are 2310mm x 875mm

When I try to run a other op like a slot the dimensions are perfect and the problem does not occur. Is this maybe a porblem with arc mode or distance mode of some sort? or maybe in my cam skills because they are not great.

I am really desperate because I can't seem to find the problem. I really hope someone could help me with this problem.

Mach4 General Discussion / Re: Mach4 y coordinates are wrong when machining

I don't think that is the problem.  Ok let's say that I have a rectangle(A) which is 200mm x 200mm and I want it on the center of a plate which is 400mm x 400mm(B). So on all sides between rectangle A and B is the distance 100mm if it is correct. But the problem I now have is that the A is 200mm x 200mm and the distance between A and B is in the x direction 100mm on both sides. But the distance between A and B in the Y direction is 99,5mm in the upper part and 100,5mm in the lower part.

So if the counts would be wrong rectangle A would not be 100mm x 100mm am I right? And the strangest thing is that when I try to run a small part the problem never occurs. And then when I enlarge the part with the parameters in fusion360 this problem occurs. I only need to change the stock size, because I have constraint the sketches to the stock so it adapts.

Hope this explanation is clear. Thanks in advance and for the former reply

Mach4 General Discussion / Mach4 y coordinates are wrong when machining

« on: August 07, 2019, 09:26:02 AM »

Dear people,

Iam trying to mill a large pocket in a piece of wood which need to be the same distance between the upper outside stock and the lower outisde stock. The gcode is correct in fusion360 but when I machined the part the lower dimension is 9,5cm and the upper is 10,5 mm. When I try a smaller part with the same feature it is correct. So looks like mach4 shifts the y coordinates when it starts the program. The x values are the same as my drawing but the Y value is shifted.

It is strange because when I try a smaller part, with the same feature and adjust the feature dimensions to the stock size, the problem does not occure

I use g54 to define my work coordinates. Could someone please help me. Iam really lost what it could be

Thanks for the reply. I just edited the names to match somewhat in English. I use the csmio controller and io so maybe that's why the coils and contacts came up blank.

The csmio has an internal diagnostics and io monitoring window. The pcm does work with that diagnostic window from the csmio. I haven't tried it with the mach4 diagnostics because I use the internal csmio window.

Hope people can figure out the program for there setup otherwise feel free to post here.

Guys, Here is the Pmc file for the ways oiler with english variables. The pump is enabled after 15 min controller enabled time. The oilpump will be activated for 1 minute.

Inside the Pmc file are two time on delays. The upper on determines the time interval that activates the oilpump and the lower one sets the time how long the oil pump is enabled.

Hope this helps some people out.

I forgot to add that the program is made to control the outputs on an output device. The device I use is the csmio-ip/a. I could send the pcm program via mail if someone wants it.  Then you can change the outputs to your device and makes it easier to change the time of the timers.

Just let me know if you want the pcm program. I will change the names/variables to English instead of Dutch.

For the people wanting to use a similair code. Here is the lua file. I can't upload a pmc file.

The program is activated when the controller is enabled.  The first timer will determine at which interval the pump is enabled and the second timer sets how long the pump is activated before it will be deactivated and the interval timer will be reset.
The timers are both set to 10 seconds.

Why not do a Bing or Google image search for
"ladder diagram for way lube timer"
and then emulate the ladder code using the PMC scripting/ladder feature in Mach4 to write the code for you?
Might help you learn and understand how timers and lua works.
would be a good test and lesson.

Thanks I totally forgot about the pcm editor. Tried a diagram which turns on when the controller is enabled and then generated a Lua code.
The code worked flawlessly. Thanks again.
