Hi Guys

After a couple of attempts of machine building , suffering 1 workshop build where my work got trashed , subsequently moving to a new workshop which suffered with slight damp and thus having the machine start to rust I now have turned a room at home into a small workshop - so no damp problems.

I am now ready to start again - I have been donated a few parts - when they arrive I will update the log with pictures and specifications and have another chat with Hemsworth Lad re building the machine ( a very helpful and knowledgable chap who lives about 8 miles from me).

If anyone has any bits and pieces they want to donate to the cause - that would be appreciated .I will reciprocate with help on any guitar/amp related projects (I have loads of parts etc knocking about).

Anyone in the Barnsley area interested in a chat re cnc or guitars PM me.

Cheers Tony

Control signal interface:

Figure 1 is a wiring schematic of the drive
1. the definition of control signals
PUL +: step pulse signal is input side or the positive pulse signal input positive terminal
PUL-: the negative input of the negative input pulse signal or a positive pulse signal
DIR +: stepping direction signal input to the positive terminal or negative pulse signal input to the positive terminal
DIR -: stepping direction signal input of the negative side or reverse step pulse signal input negative terminal
EN +: offline can reset signal input side is
EN-: offline can reset signal input negative terminal
Offline enable signal is active, reset drive failure to prohibit any pulse, the output of the drive
Power component is turned off, the motor holding torque.

2、Control signal connections
PC control signal can be high, also can be low effective. When active high, the control signal
The negative side together as a signal to active low, positive side of all control signals together as a signal common.
For example, open-collector and PNP output interface circuit diagram is as follows:
Figure 2. Input interface circuit (common cathode connection)
Note: the VCC is 5V, R short；
VCC value of 12V, R 1K, more than 1/8W resistor;
VCC value of 24V, R 2K, more than 1/8W resistor;

New CNC Type Long Nose Die Grinder

24000 r/min

680W

On/Off Switch only, no variable control

6MM Collet

There is also a box of Astrosyn X173H stepper motors (a total of 6 units - so some will be up for swaps for stuff to help me build the machine)

A good start

[Drakkn]

Ok - power supply at the post office waiting for collection , rail supports ordered , couplers ordered , carbon steel rods ordered - getting there slowly.
Just linear bearings , drive nuts , bearing ends , trapezoidal threaded rod , some mdf , nuts , bolts and cable to be sorted next.
I have the design on a scrap of paper , It is a sort of jrgo mixed with other stuff I have seen and read about.Footprint will be approx 1M x 500mm.

[Drakkn]

Power supply collected , steel rod and trapezoidal screw collected from a local source - way cheaper than marchant dice.Ballscrew nut ordered for testing.

Thinking about changing the design to using box steel/aluminium.

What gauge electrical cable are people using for the electronics.

[Marti]

I have hybrid motors ... how is that driver working out for you?

[Drakkn]

Hi , Not done any more work on the build - but will update with the motor testing soon , nearly got everything now , not decided on which connectors i will use for the leadscrews yet.

[Drakkn]

Well after a long break my machine is suddenly starting to look like being near completion.As always finances get in the way.
Here is a picture of what it looks like currently - Foot print is 1000mm x 700mm - actual cutting area I will measure at some point.

[Drakkn]

Frame is now built - Taking ages on this build due to only being able to buy bits when there is a bit of spare cash

[Drakkn]

Next stuff to order will be

1 piece SFU1605 Ball Screw L1000 mm+1pcs Ballnut+ends machining

1 piece SFU1605 Ball Screw L610 mm+1pcs Ballnut+ends machining

1 piece SFU1605 Ball Screw L250 mm+1pcs Ballnut+ends machining

3 pieces CNC Ball screw Nut Bracket Holder Steel For SFU1605
1 set BK12 BF12

More update soon

[Drakkn]

Things moving on nicely , I am having a few parts made here in the uk for the build , whilst waiting for the ballscrews to arrive , Also a 300w spindle/bracket/psu and speed controller will be with me in a couple of weeks .Once everything is here I will finish the build , pc is ready , I have all the electronics so I will do a test soon just to make sure they are working and that I do not get any nasty surprises.

[Drakkn]

Right then guys - the machine is now assembled - Just have to sort out the electronics and hopefully start cutting soon .
It's been a long time (Frustration and money) slowed down the build . I have evrything , spindle and mount and psu arrived the other day so soon it will be testing time.

More to follow .....

[Drakkn]

Update - motors up and running and tested - for those of you out there with HY-JK02-M 5-axis interface board - the pin outs are wrong in the manual.It took me ages on testing to get it right

Configure Pins for Axis (Stepper Motors)
The next tab is "Motor Outputs", this is where we tell Mach3 what pins to monitor in order to move a stepper motor. From our JK02-M5 table we know PIN:
2 is X Axis Step
14 is X Axis Direction
16 is Y Axis Step
3 is Y Axis Direction
7 is Z Axis Step
8 is Z Axis Direction
6 is A Axis Step
5 is A Axis Direction
4 is B Axis Step
17 is B Axis Direction

Enter the correct Pin number into the table next to the corresponding Axis, "Port" number is always going to be "1" as we only have one port. In the "Enabled" column, click the red "X" until it changes to a green tick. Enabling and item activates it for use in Mach3. You can also use these panels to stop using an item, simply hit the green tick in the "Enable" column and it will revert to a red "X", the settings can remain.

Also

Enabling The Relay circuit
On the above panel is a field called "Output #1", this is the configuration for the JK02-M5's onboard DC relay. Again from the JK02-M5's pin-out table we can see pin 9 is connected to that relay. To allow Mach3 to enable/disable it, change the red "X" to a green tick in the "Enable column next to "Output #1", "Port" to 1 and Pin Number to 9. Click "Apply" in the bottom right corner to save and "OK" to exit the menu.

The motors now run quietly and smoothly - more updates to follow

Just a quickie

[dodger889]

Since this is my first time looking at your design. I'm thinking that your upright supports are going to be way undersized for anything but styrene foam. I'm guessing you are planning to cut wood. Your over all design is going to have a lot of flex on all the axis.

[Drakkn]

Hi , It's main job will be with wood , and hopefully aluminium to - as for flexing currently none is detected- The rails are 20mm dia from marchant dice.

[kmyerslp]

I will have to agree with dodger889 in the fact it wont do well with wood let alone aluminum. If you are planning multiple very shallow passes then maybe it will work. I would test a "load" by pessing in all directions on the bit while it is centered on all axis' and see if you get deflection.
