It travelled very fast peter.

If anyone has DM542 internal circuit board diagram then plz share. It can be a start point to figure out what is wrong with it.

looks like the signal is getting interrupted inbetween. I am no expert but are you running other process on the pc? This may cause interrupts.

Hi,

It should work with less torque. This is what I have heard. The magnetic field collapses when you takes the rotor out and it has to be re-established when putting in. The magnetic field is...

Hi folks,

Greetings.

I have newly built CNC router with Nema 23 (425) motors and DM542 driver. I have used 2 stepper motor arrangement on Y axis. One of my driver stopped working mid-flight....

Hi Peter,

can you share your wiring diagram for the whole setup. Recently my one of the drive stopped working and the vendor says its gone. The red light blinks every 3 sec when it powers up....

Keep it going Peter. 250mm is huge shortage. I generally triple check my dimension before ordering of even cutting/machining out of stock. Was bitten couple of time so I be careful.

keep posting,...

One issue I have encountered. Need help!!

while I was machining, one of the Y axis motor stopped. I checked and the driver has 1 LED blinking. It blinks like 1 time every 3 second. I tried...

Excellent idea mate. I will be on a lookout for a small lathe 3 jaw chuck. Thanks a lot for this idea.

Thnx Peter. Didn't think of it. That's solve the problem.

I have been fiddling around with the Aluminium machining. Recently added air cooling and changed the Mak mounts to a better and stronger one. Also to reduce chatter, vibration and tool deflection,...

Good going Peter, came back to check your progress on the machine. what is the distance between those thread inserts? I kept it about 7cm and I still sometime can't fit my work.

Forgot to update. Got my MAK after 22 days after lot of push and follow ups. They didn't charged me any penny. The router is back to life and working nice. I will have to make new mount thou to do AL...

Hi Stuart,

The ball screw was bent slightly at the middle and could have fixed it by mounting it in the lathe and then pulling it one side to counter the bent. But I got a replacement ball screw...

So the dismay continues. Its been 2 weeks since I sent it to the service center and I am yet to get it back. The service center keeps tossing surprises. I learnt that they don't have field coil for...

Beautiful it looks. the long shiny aluminum plate. Big long router fascinates me. May be someday I will build one too once I have enough experience and space available.

I visit this forum, read...

The clamps were horizontal as I mounted. I will do as advised, inclined and bolt moved to center to have equal pressure on both ends. I see the Z plate on which the route r is mounted is thin (10mm)...

Do you suggest something like this?

Since my mak is away and is not coming back till wed, I am fine tuning the router setup and making some changes. One thing hit me is if the tool got loose and it applied force on mak which later got...

Thanks peter.

The calculation make sense to me and at the same time gives me some idea on how to machine and what to expect. 0.3mm DOC was me being conservative or say uncertain as this was a test...

My tool bit was not long, so out of necessity I had not inserted it too dip. If this happened due to tool coming loose, may be when I changed the tool mid-flight I didn't tightened it to the required...

The collet they give here is 6mm and 8mm. My 1/4" shank tool doesn't go into it. Only 6mm would go in 6 mm collet.

On feedrate, I checked it was 500mm/min in solidworks setup and I was running it...

Thank you Mactec. I got that shorted out.

But a new problem came to the fore. Screwed my Makita Router. I was test cutting the aluminum at 0.3mm depth every pass at not much high velocity...

Hi Loy, you can create a thread specific to this to get right answers.

Hi Mactec54,

You mean, to mount in lathe between center and then use jack underneath to remove the bent? is that safe?

I have been experiencing few things while I am learning the mach3 and the...

Damn!!! I was having misconception then.

Unfortunately I don't have these. sometime back I had planned to make a press using bottle jack to fit bearings and similar application. The project didn't start but i do have 5 ton press lying...

I think I made some mistakes in loading the balls in the screw. The screw is gripping which is causing wobble. witch hunt continues.

Yes, I believe you are right. I loaded all of them except one ball. It was lying around and I couldn't see it untill I was done. But that ball screw nut is on z axis and is happily turning well.

More info:

I pulled out the screw and mounted it in lathe to see where is the issue. The screw seems to have a bent in the middle. The point where I kept it in chuck and machined is still at...
