Hi Momentz if you are using dual rack and pinion you could stagger some middle legs to the inside of the tube to stabilise the centre of the 3 metre lengths and attach the rack to the underside of...

Thanks for the reply wizard,so far I have only had an issue on startup it usually lasts for about 30 to 60 seconds then everything seems to smooth out. The last time I ran the machine was on a 3d...
I'm wondering if anyone can help with a issue I'm having when starting my controller. I have a g540 control running it with mach3 I get axis shuttering on all axis when I do moves in any direction on...
Hi Wayne I no what you mean about no torque increase it was more to do with lowering the ballscrew speed when the servo is ran at high speed,thats why i opted for the 10mm pitch screw and also the...
Hi again mate ,so I would think a rotating ballnut like your set up. I got my quote today from dmm 4 axis .75kw AC servo kit $3160 including shipping,I wonder how much our government will throw at it...
Could anyone tell me what would be the maximum speed I could rotate a 25mm diameter by 10mm pitch ballscrew . The length is 1600mm 63" between the bearing mounts ( bk and bf 15 mounts ) thanks. Danny
My servos on the low cost cnc retrofits unit are 600 oz
Looks awesome Wayne but you have thrown a bit of a spanner in the works for me,I've spent my day looking at all different systems, I'm now thinking ballscrew due to the fact that I want to cut and...
I think those speeds are achievable but there is a lot to consider for instance motor speed ballscrew diameter and pitch , a servo spinning at 4000rpm on a 5mm pitch ballscrew will give nearly 800...
Take a look at dmm tech they have ac servo style systems I think they range from 200watt upto 2 kw prices look like they would fit into your budget.you would be suprized at the performance of some...
Hey mate I had a similar problem with a 6040 cnc router.i found it was ****ty motor cabling,how I found this was testing the z axis up and down it behaved in a weird way,it would work then stall then...
Hi Wayne to be completely honest im impatient ;) I do want to setup a tool change spindle at one end of the table and don't want it to take forever to get there,the rapids im talking about are a wish...
hi Ger21 in your calculation you suggest 125pounds of force then divided by2=62.5 pounds for each motor =1008 ounces I don't understand why you have divided it again giving 504 ounces, isnt the 1008...
Hi Wayne just had a look at the lead shine stuff pretty interesting have you used this stuff before. I don't no to much about the electrical side of cnc , I'm very interested to hear how it works out...
Im currently building a heavy cnc router and was after help on what system I should run,my gantry would weigh around 300 pounds.im looking to cut a fair amount of aluminum hence why I'm building it...

hi Greg I also have a 6040 cnc a word of advise is go straight out and get a gecko g540 .I spent weeks of frustration on that blue controller if it wasn't one problem it was another from day 1 the x...
Hi Ahren the motors I have got they don't sell anymore,they are 38volt ametek motors not much info on them that I can find .what I no is they are 38 volt 12 amp 600oz/in and around 1000rpm and they...
Thanks for the reply Dale. The issue I have is I already have the controller and want to put it to use . I did some calculations but don't no if they are right,I worked out the motors spin 1000rpm...
Hello all I'm currently in the process of designing myself a heavy router the problem I have is I'm unsure of what size motors and reduction I need for a rack and pinion. I have myself a 20amp servo...
