step and dir pulse problem Mach3
Hi all,
New to forum and look forward to reading and gaining a little info.. Firstly i have the 6040 and have had nothing but trouble since i bought it 2 months ago , already had a x-axis replaced due to constant banging, now my problem is mach3 and the step and dir pulse... i change them but mach3 doesnt save them and they revert back to 0 and due to this my machine is missing steps badly. I've fully uninstalled and reinstalled mach3 but it still wont save so i continue to have this problem... Any help much appreciated.

That's a new one.
You are saving every axis individualy as you do it on the page aren't you?.
Not just going from page to page changing every axis and then trying to save?.

Re: step and dir pulse problem Mach3
If the copy of Mach3 came with the machine, is it a genuine licensed copy? There are quite a lot of "pre-licensed" copies around and they are notorious for giving weird results and inexplicable problems. One possibility is to download a genuine demo copy of Mach3, use your existing configuration files, and test to see if that works. Demo versions are limited in the length of gcode they can run but are otherwise fully functional so that would see if there is a Mach3 problem or not.

it was given with product and looks like a pre-licenced copy, will download a demo copy and try that and let you know how it goes.

Re: step and dir pulse problem Mach3
Downloaded a Demo , and it let me change and save settings in motor tuning.....But now the machine doesn't move, if i use arrows on keyboard it shows it moving in the DRO but its not actually moving , i know i must have a setting wrong in setup so will try and figure out which one.

Re: step and dir pulse problem Mach3
If you connect using USB then you will need a plug-in for mach3 and possibly drivers for the device.

Hi Jazz ,
yes its usb connection , when i first got a couple of months ago all worked fine once i installed mach3, never really cut anything due to it missing steps and waiting for a new x-axis to arrive, installed that and was still missing steps so i tried to alter settings in motor config but when i saved it just kept reverting back to 0 , so i decided to uninstall mach3 and re-install but now it lets me change and save the step and dir pulse but the motors dont actually move even though it shows them moving in the dro in mach3. so now i need to try and get the motors moving and then finally be a happy man. Cheers

Ok, then you will need the Plug-in for the controller you are using. This is why the DRO's are moving but not the machine, mach3 only provides the driver for the parallel port so any 3rd party motion controllers need to provide a piece of software called a plug-in that tells mach3 how to talk to the external motion controller.
To be honest you'll probably find it easier to start again and use a better controller because the Chinese USB controllers are notorious for being rubbish and USB it selfs isn't very stable or reliable for CNC due to being easily affected by electrical noise. Many people upgrade to an Ethernet-based controller.
Personally, I would replace it with an AXBB-E controller which is a great controller at a good price, it also has its own software called UCCCNC which is much better than mach3 and also made by the same people who make the controller so it's much better integrated with the controller and it's fully supported, unlike mach3 which is no longer supported.
The AXBB-E will also work with Mach3 if needed, I just wouldn't because UCCNC is so much better.

Re: step and dir pulse problem Mach3
Cheers Jazz,
Found plugin and installed and all is working , only slight problem is that when it goes back to home its out by a couple of mm, did a cut on a small file that uses 4 passes and it looked fine , no missed steps as far as i can see not like before when it went out by miles. Anyway going to see how it goes before i decide if i am going to change anything so
thanks for all the advice.

Hi Jazz ,
Been a few months and still having problems, so will purchase controller you mentioned the AXBB-E controller ......Is that all that I need to purchase.

To use the AXBB-E you will need 5Vdc and 24Vdc in the control box so you might need a PSU depending on what you have already. You can use 12Vdc in place of 24Vdc if don't have it, Some people use an old PC power supply that has both 5V and 12Vdc outputs.
Other than that all you need is an Ethernet cross-over Cable if running directly to PC or a standard Ethernet cable if running through a network hub or Switch.

Re: step and dir pulse problem Mach3
You don't always need a crossover network cable, a lot of network cards will do it automatically.

Same with the UC300eth (same controller base as the AX).
Pretty much guarantees it's going to work.
-
Re: step and dir pulse problem Mach3
Ordered the AXBB-E today, so looking forward to recieving and having a go setting it up, will post pics of the insides of the controller box i have tomorrow so people can tell me what i need and dont need and give me any help i need installing new card.
Cheers

Re: step and dir pulse problem Mach3
The network card does the crossover automatically. You can use a normal patch lead IF your network card supports this function. We'll at least that's my setup.
I think the network option is called Auto-MDIX

Many do, yes. Likely get the odd packet loss which is not good for cnc even if slight.
However, why bother arguing with the user manual?.
It says use crossover when connected direct so why not do it?.
Not exactly expensive.
I made one from some cat7 bits I had.
Carefully set it all up and was moving in no time.

Just received my AXBB-E and i also got a 5v and 24v psu so all i need to do now is panic as i dont have a clue what im doing......Help
Attachment 30861 do i keep this board as it has the X Y Z axis attached
UPDATE.....Have connected Axbb-e to the 5v and 12v power psu and also connected network, so now need to build a bigger controller box so all will fit in.

That is an all-in-one board with controller and motor drives combined so you can't use it because you can't control the drives.
To use with the AXBB-E you will need separate drives.

Re: step and dir pulse problem Mach3
My stepper motor has this on it NN MOTOR 57HS7416-15-14B 80 Does that mean anything , when I did a search it didn't come back with much except nema 23, so do i order drivers for a nema 23.

Depends on what you want to do and the motor spec. Model number not showing anything so double check you have it right.
What are it's dimensions, that may also give us a clue on it.
Personally, I never run my nema23 motors below 60vdc anymore which requires the nema34 drivers DM860T instead. The velocity you can achieve is so much better.

This is typical of Chinese machines as they fit oddball motors which you probably won't find any info about. However, doesn't really matter too much because you will only have at best 36Vdc from the PSU so any drive with a 50Vdc max rating will work for you. Because you can't tell the motor current a little trial and error will be needed on the amps but this is no big deal as they will just run hot if too high and stall easily if too low.
These will work fine for what you need and will work miles better than what you had before. But before buying it's worth checking the voltage coming from the PSU

If you find that your max velocity is below what you would like, swap out the 36v for a 48v.
I'd have gone for the DM556:

Re: step and dir pulse problem Mach3
I use DM542T drivers at 36V on a pair of 3NM NEMA23 motors to pull an 800mm wide welded steel gantry with a 2.2KW spindle on it. It's fairly weighty but will rapid at over 10/min with reasonable acceleration so they'll probably do.
However, there is always a case for spending a bit more on something over-specified for your present needs if you might want to upgrade other parts in the future. It's a balance between spend more now to save in future.
To get a bit more info on the motors you could look at the spec of similar sized motors from stepperonline and others. Measure the winding resistance of the motors you have and look for a match in both resistance and physical size. It's not a guarantee they're the same current rating but will give you somewhere to start.

Hi All,
been having a go at building onto the AXXB-E attached are some pics and would like advice as to were I have gone wrong on the stepper drives, also the 3 wires lying by the AXXB-E are from the VFD av1 grnd and +10v were do i attach these to the AXBB-E, also emergency stop and pump.
All the advice i have had up to now is much appreciated.

Be Careful if you don't know what you are doing because you can easily damage the controller if you connect up wrong. Don't turn it on until you are 100% sure it's correct, you can't afford to use a trial and error method here because you won't get a second chance once you let out the magic smoke.
I will knock you up some simple diagrams but it will be tomorrow now, I suggest you wait rather than have a go without being sure.

Ok, here you go. I have broken each down into separate drawings.
On the VFD you don't need the 10V with AXBB so just remove the wire.

Edit: My drawings show Step which is Puls on your drives.

Re: step and dir pulse problem Mach3
Looking at the first two images, I'm concerned about the polarity of the supply to the stepper driver. It appears to show a black wire to +ve and red to -ve, although the 24V supply to the AXBB is correct. I can't see where these wires go on the power supply.

Doesn't look like that on the images I'm looking at.? Maybe need to zoom in.?
Edit: Sorry just spotted you mean the OP pics, not the ones I posted last night. Yes looks wrong but depends on what it's like at the PSU.? Logic says its wrong
-
Re: step and dir pulse problem Mach3
I had replied to OP before I read your post, Jazz. Sorry about confusion.
Indeed, it depends on PSU connections at the other end of the wires but it's a disaster looking for somewhere to happen!
-
Re: step and dir pulse problem Mach3
Cheers Jazz,
no would not have turned it on and still wont till im sure , thats why i asked for help lol.
Actually had another read of the manual and spotted where I have gone wrong.

Re: step and dir pulse problem Mach3
im nearly there I think with wiring my Axbb-e , just got a few more questions.
Do I need to wire on off switch, if I do …how, or can I just plug in without it.
Wires coming from L1 AND L2 from back of VFD were do I locate these.
Is it ok to loop my 5v power supply from my 24v power supply or should I use separate supplies.
Cheers for all the advice and help..

You can have a mains on/off if you wish. I use a 4 way dis-board with individual switched outlets with separate feeds for the AXBB-E 5V/12V supply and the 36V motor supplies.
