If you have a UC300ETH, just add a pot for spindle override, and you have the best of both worlds. Just turn the knob to change the speed.

Hi Gerry....yes i have the UC300ETH, did not know about this function. Thank you for the info

I use two.
Wire them to the analog inputs, and assign them to feedrate override and spindle override.

That is great, thank you.....ps what values are your pot's?

[ger21]

5K linear

5K linear

Yaa, make sure the potentiometer has linear scale and not exponential otherwise with exp.potmeter the speed will change slowly on the turn start and will rise fast at the end of the scale.

Hi...has anyone ordered Leadshine drives from an Alixpress supplies named "Cloudray"?

I need to order drives for my next build and want to make sure they sell genuine Leadshine

Thanks
Erick

Hi ericks - I've been using stepperonline. They are fast on the technical questions and good on delivery and price. Not sure cost compared to aliexpress. Have look at them, they have been very good in my experience. Peter

Thanks Peter.....i have bought from them before, my current machine Nema34 motors are from them. Only problem with them is their shipping cost
I have been talking with them today, they say their drives are made by Leadshine....i bought one long time ago from them but i dont think it was as good as my genuine Leadshine drives.

Not much happening with the machine lately. I have been sorting and cleaning the shed. Today the dust shoe and pendant arrived. Both look good. Been busy planning to start building control panels for routers ect....
Will be using only quality parts....

Pizza oven?

Pizza oven?

Not a bad idea

I am building control panels for sale...

[ericks]

Looks like the dust problem is sorted. I am using the Kent cnc dust shoe. Had to make an adapter to fit my smaller vacuum hose. Only problem is i sized the bristles with a large bit...i might need to buy another shoe with shorter bristles for for when i use smaller bits.

Next step is to tidy things up, make a bracket to hold the vacuum hose properly to the z-axis/motor etc...

[ericks]

I did not have a hole saw or chassis punch so i used my old long way to make a large hole. Took about half an hour for this one cause its a very good quality enclosure made with thick plate.

[ericks]

I need to cut holes/shapes into the control panel gland plates....initially i thought of making new gland plates from aluminium. So i tried to cut the steel plate with my router. The test cut worked perfectly i cut at 1000 rpm.

Another quick cutout

Hi Ericks - Do you have a dial gauge and a scale? Could you check the stiffness of your machine? eg say you push the collet with 5kgf what deflection has it got? Interested because you cut steel so the machine must be very stiff. What was your depth of cut DOC? Peter

Hi....i don't have a scale unfortunately. The depth was only 0.1 mm but i did cut at a fast feed rate. My machine is very rigid, i do have options to make it even more rigid if required. I made small cuts cause i was running the spindle at a very slow speed and i was afraid it might stall

[peteeng]

Thanks Ericks - I don't think your machine needs to be any more rigid. Its Uber rigid now. Yes you do need to run slow rpm on metals. Great machine. Peter
