I am living in Toronto and happily own an HY-3040 cnc machine. First time I'm to buy a vacuum table and pump. I'm not that good at physics and don't know what parameters the pump must have and also...

Hi,
My HY-3040 cnc machine is only 1 year old. In a new project, it started to make position error. They happen only in Y axis and always the same: after running some cycles, I do a re-home and I...

HI John-100

Thank you really, I'd sure study the condition and do as you suggested as it really makes the job easier: being able to control spindle from the PC!

Thanks again :-)

John-100
Thank you for pointing me to improvements. You mean that even though there is a VFD, I can obtain the type of controller you pointed to and put the PC in interactions with the VFD that has...

John-100,
Thanks really for detail instructions.

I successfully replaced the new driver.

I will go for a new breakout board with opto-isolators to secure the printer ports from possible...

Thanks everybody, I'd go for an oil less low noise two stage pump with at least 2-3CFM, and one that can pull at least 25"Hg vacuum, what I learned from you ;-)

John thanks for the post,

The spindle is 1.5KW with a VFD. I found out that no signaling happens between the spindle control boxand breakout boards. I found also a post on CNCZone mentioning of it...

Hello,

I am replacing a burned breakout board with a new one but I have two main problems:
1. knowledge insufficiency
2. no documentation!

Chinese seller sent what he calls "manul", but in...

I decided to perform the replacement as it seems that it is not very hard. I made new post in the forum asking help for the pinout conversion between the burned and new breakout.

Hello!
Please bear with me!

I am about to replace a burned breakout board of my new HY3040 cnc machine with a new one I had available. I know that the new one is also a cheap board but until I...

It was just a simple foolish mistake I'm now sorry about it!

Fortunately, I have a brand new breakout board available but also without documentation and I'm not sure if I can replace it!

If...

Hello,
With lack of knowledge just by what I read from a post in the forum I tried to setup probe for my HY3040 cnc machine I just got :(
Unfortunately the information about the probe was not...

Hello,
I just received my new HY3040 cnc machine I got off ebay and without any problem had a run test. After that I went to setup probe but well, not enough knowledge to find it out without help....

Hi,
I'm going to first time buy a vacuum pump and make a small vacuum table DIY. I have not enough knowledge to choose the pump, but by some googling I found this one on ebay:

Hello everybody,

I just received my 3040 cnc machine in Toronto and now need to get a vacuum pump but being new in this city I have no idea where to go. I tried searching by google and some local...

MrMag, thanks, so you mean, even no need to provide invoice with price then? (in case mentioning as 'sample')

P.S. is it belivable that from China a ~100kg package is sent as a "sample to be...

Thank you Jeff,

After your reply I contacted the seller again and yes, they send by DHL and the seller clearly pointed to payment I have to complete at my door to the carrier for the custom...

Hi,
I've used Mach3 with my 6040 cnc machine now for some 5 years with no problem. Same configuration was applied if I changed my computer and installed a new version. Now I've had a crash and again...

Hi,
I have my mach3 with the module for tool setting on the surface of the job. First time I have this situation that I start the z axis toward touching the plate to which I connected GND and I see...

Thanks for all the advice and clear instructions. I've no more questions. Also the videos helped a lot, I'm now sure I must go for vacuum bagging and get pumps and all needed items to get fine...

Hi,
I'm newbee to foam molding. I'm going to make one, for the first time and have 2 questions:

1. I'm going to cnc machine it and this foam-spray is being sold in different types. What...

I'll do as you say, so that means such a process I guess:

1. making male mold from wood (or if I'm lucky enough, foam!)
2. preparing the mold
3. coating with gelcoat
4. applying fiberglass to...

Thank you very much, after these preparations I'm ready to try hands first time :)

Does that mean that even after finishing the carbon fiber coating process and then taking the finished part out, I still can work on surface, with sand?

If so, then what kind of polish should I...

Please have a look at this video, do you mean this foam used there (spray)?
How To Make A Disc Wheel Tutorial - YouTube



Is vacuum bagging obligatory? I don't have pump and other components...

I've seen cnc machine cutting foam, but never did such because I don't where to get foam and what type, I only know where to get foam-spray.

Could you please tell me what foam I can get for that?...

Thank you, but then, again, I first must use PVA on the wood before applying gelcoat, for fiberglass making, right?

If so, then I suppose that I must go like this:
1. make the mail mold by cnc...

Hi,
I have a cnc machine and the easiest way for me to make a male mould for then coating it by carbonfiber is by using wood. Is it practical, or is there a process that makes wooden mould usable...

SOLVED!

Big apologize people! I had simple mistaken wiring!

I have to be perhaps shy for that taking your time! Just reversing cable and all got working.

Well thank you all I learned from...
