How Do I Send Messages To The Group?
What Best Practices Do You Recommend When Posting Messages?
To send a message to the group and start a new topic, send a new email to emco-cnc-users@groups.io or login to groups.io, select emco-cnc-users from the pull down menu at the top of the page, and click on "New Topic" in the left side menu.
When using email to send a message to the group it must come from an email address you have registered with groups.io, either as your main address or as an email alias. Messages from unknown email addresses aren't allowed to avoid spam.
If you want to reply to a post, things get a bit more complicated.
emco-cnc-users is configured to reply to the entire group and to the sender by default, but it seems that every piece of email software handles things differently, so how the reply options are configured doesn’t actually assure what happens. When you hit “Reply” or “Reply-All” in your email tool, examine the TO line to be certain the message is going to the place you want it to go. In general, your reply will at least go to the entire group, so be careful. Edit the TO line in your email to remove the group if you want your reply to go back only to the sender.
Also note that at the bottom of any message sent to the group there are several links. In most cases, among those links are “Reply to Sender” and “Reply to Group”. (There is an exception: if the sender of the message sent it in plain text format, those two links will not be present. The reasons are technical and don't need to be included here.) These will do exactly what they suggest, but don’t include the message contents in the reply.
Some best practices:
With a new topic, start a new email thread. Don't just grab a random message, hit “reply”, and add unrelated contents to the message to start a new thread. That is hard for others to follow.
If you get the message digest rather than individual emails, there are buttons in the digest messages to let you reply about a particular message. Use those! They help everyone know what you're referring to with your reply.
If a thread gets long, please delete much or all of it – particularly pictures – when you reply.
When replying, look *very* carefully at who you are replying too. Any email based system like this makes it possible to accidentally reply to the entire list when you meant to reply to just one person. Check those TO and CC lines every time you reply to be sure your message is going where you want it to.
On message content:
In short: be nice, concise, and avoid giving offense.
When writing about some topics, be sure to provide all the relevant details. In short, try to tell people everything they need to know, rather than make them ask you for more details.

Re: Manual entry of MSD values

Type MON first, this is the user monitor Select parameter O40 and set it to O40=0 if it's a TM02 control (raised mechanical keys) or parameter L0 to L0=0 if it's an M1 control (flat plastic keyboard) To change the parameter use the CE key to clear existing value, enter new value then press enter. Press reset to close the monitor then try the full monitor again. The alarm 460 is normal as the machine hasn't been referenced yet. Dan Sent from my Galaxy

Don't press enter until you've completely typed monitor. The letters over writing each other is normal. Dan

Manual entry of MSD values
AsherMade
I recently got a VMC-100 with missing MSD information. When I turn the controller on it boots up into edit mode, with the below codes:
alarm 780: safety lock active. alarm 460: reference position active. From what I understand this means the MSD is missing. This makes sense as the machine has sat for several years without being turned on (battery on CPU board is completely dead). I do not have the MSD tape and could not find any MSD sheets inside the machine controller. I found a pdf online of someone else MSD print out I wanted to try, but cannot enter the monitor mode to enter them. I'm told you are supposed to type "MONITOR" on the edit screen, but I don't seem to be doing it correctly. When I use the keypad and type out the letters I cannot get the letter to stay. So when I type 'M' and then try to type 'O', the 'O' overwrites the 'M'. I tried hitting enter after each letter, but no success. Is there a different button that must be hit to move to the next character? I can enter a letter and then numbers and the word does write correctly, for example I can type "G98".

Ship Anchor for free - C5 motor
Chile Bike
I have the DC spindle motor for my C5 that works, spins and vibrates after the balance mass on the armature let go. I made a balancing ring between the commutator & rotor iron with m6 slugs to spend forever trying to dynamically balance the thing, but ultimately without success. The treadmill motor works fine. So the C5 motor is headed binwards, unless anybody wants it for the cost of delivery.
It seems a shame to skip it, but it needs dynamic balancing. sdk

Re: Request For EMCO C5 Lathe Mk4 ROM Code. ( FAO Dieter)
Dieter
Hello
If so, a good way of fixing simple processor boards is to take a CPU chip & hardwire the data bus to nop instruction - usually 00Thanks for the help, but it's not to fix the board but to "upgrade" it. I decoded the whole address range with a latch trap by probing on the CS of all components. I want to use the 16 bit features for the math of the 65c816 and the build in memory bloc move, but it still would require 7 clocks , much slower as a 6844 at 2 clocks / byte but here I must add more hardware.(intermediate memory for reading / writing) therefore the 65C816.

Re: Request For EMCO C5 Lathe Mk4 ROM Code. ( FAO Dieter)

Hello sdk
I really like the thinking with this. :-) The EMCO is 6502 based but that does not necessariy change the principle. My first reaction is that it is not quite perfect with a 6502 or 6800 because the NOP instruction is 01. So, a reset will vector the processor to 0x0101 - but that is ok. Even this could be fixed with some logic between the address bus and the low data bit. It should give a simple test for basic CPU operation and also maybe a fast way of obtaining the memory map for an unknown board by probing the peripheral "chip selects" . TBH, I don't do this sort of stuff very often any more. Also the availabilty of Arduino + similar stuff means there are fairly easy, v low cost ways now to build a "test harness" for boards or chips. But I do like the idea - very neat. I will have to try it out when I get the time. :-) Regards JG

Should you fail to have a spece CPU, you can elevate it in 40pin dip sockets with suitable doings going on in intermediate sockets. Of course.

Re: Request For EMCO C5 Lathe Mk4 ROM Code. ( FAO Dieter)

I see all this stuff with CPU boards - this is a 6800 microchip, is it not? If so, a good way of fixing simple processor boards is to take a CPU chip & hardwire the data bus to nop instruction - usually 00. Bend the data bus so that the pins don't connect the CPU board. The CPU loop will then cycle from address 0 to oxffff & around again, without change. You can then scope the memory & peripheral addresses - no seperate i/o space as I recall and look to see the thing is doing as expected. sdk

Re: Compact % CNC
Dieter
Hello
You can adjust the max.feed when reaching the end position of the feed poti, It alters however the min feed, but it doesn't matter. If you go to far you can loose steps so adjust it by using a dial indicator for X and Z travel to the max reliable speed and then go a bit lower for safety margin. The CPU with the DNC connected (without the stepper board) draw about 1.2 A, so the slightest contact resistance cause problems. Dieter

Re: Compact % CNC
abarano@...
Hi,
yes, it is now clear to me that the 5 volts must be present in order to avoid interference. I will also post photos ... just don't understand yet how .... had already tried that!
In addition to the poti feed, there is an adjusting screw on the circuit board .... what exactly does it do?
greetings and thanks

Re: Compact % CNC
J G
Could you post some clear "high-ish res" pics of the "lower" part of the board (CPU, ROM, RAM, PIO area) - component and solder side - from a slight oblique angle ideally.
They might be useful in helping diagnose the problem. Regards JG

Re: Compact % CNC
J G
A step forward :-)
The part success you have had points in the direction of a power supply issue. Dieter is quite right to suggest checking the the voltage on the CPU - and possibly other major ICs + maybe the "reset" circuitry. Do you have meter to check the voltage accurately ? ( and also the current drawn ideally) There is little point offering more advice until it is confirmed that the 5v is "in range" and stable. If the 5v supply is marginal to any of the ICs on the board then all types of odd errors will occur - especially when the MPU board attempts to interact with external devices or perform intensive memory access, etc etc etc. What is the problem with the tape drive board ? Did it work before ? It would still be useful to know what the conditions of the failure were - sudden or gradually worsening. All these things provide clues to diagnosing the problem. Regards JG Off topic : Hello Dieter :-) Good to hear your progress. I am looking forward to more on the oiler - would be v useful. First the automatic oiler - then the automatic oily mess "cleaner up" ;-) :-) :-) How goes the software development ? - or have you paused that for now. I have not been able to do any EMCO related stuff lately but hoping to get back to it soon and follow up properly on the info you provided.

Re: Compact % CNC
Good day, I have now checked the 5 volts again and seen that the contacts on the board may be bad.

Re: Retrofit consult
Richard Engbersen
I am ordering all parts, still several are pending, while I am preparing the retrofit of my EMCO F1 CNC. See attached picture of parts that have already arrived. QUESTION: any of you can advise how to connect the WPM controller for the tool spindle to the controller in such a way that I can control the RPM from the program? Parts picture attached. Thanks, Richard Op zo 31 jan. 2021 om 14:10 schreef <gonzalezpineiro@...>
Interesting project Richard, as I am also retrofitting the Emco F1 (although with other electronics) so we can exchange data. Will you leave the original spindle motor? I'll leave it for a while with an HQ-SXPWM-A type drive, which I haven't tested yet. You can see how the project is going in the thread "emco f1" of this forum or in

Re: Compact % CNC
Dieter
Hello
JG already mentioned the most common faults, however measure the 5V directly on the CPU. I needed to replace the 5V pins on my test F1-CPU. When slightly moving the plug the voltage alternate more than 0.5 V and the CPU freezed and when not moving it never reached full 5V, the contact resistance was to high. No chance to clean the pins, I had to replace them. (Also described in the maintenance manual) In the manual is a good description about electronics faults. Look also for the capacitor in the reset circuit, when defective the CPU freeze in reset. off topics: JG, I'm still working on the oiling system, the pipe work and oil grooves are finished. First tests seem promising, but what an oily mess! Need to reassemble the slides, install a pump and end switches. Dieter
