Sorry, I forgot to mention that I mill aluminium 6082
Dear all,
When I do circular milling operations with small end mills, chips tend to weld to the endmill until it breaks. It happens even if a drill a pre-hole before using the end mill to make it...
Hello,
I am upgrading my cnc milling machine with better linear rails and a ball screw instead of the lead screw I was using. Now axes runs much smoother and nicely, but when I fit the spindle, the...
Dear all,
I have some experience on 3 axes done with my CNC mill, but now I would like to jump to 5 axes and I have a doubt about the workpiece alignment.
On 3 axes I decide the origin on my...
I had already tried to use that calculator, but the result feed is about 500 mm/min that is about 25 times more what I am using, I think it is too extreme. Furthermore it gives 4500 RPM but with...
I am starting to use my homemade milling machine with a 2.2 kw chinese spindle. I need some help about the parameters to use to drill holes with standard HSS-co twist drills. I have tried to drill...
I confirm I am using v.1.2111 that has compensation mode. I have done further tests and I sort out that the compensation is applied already at the last movement before the G41/42 command line. This...
I have tried that on UCCNC that is the control software of my milling machine...
Thanks for your answer and for the codes. Anyway I have tested both with my controller software (UCCNC) and they both give me issues. Do you think it is a software problem?
Dear all,
I am starting to learn machining with Catia.
When I define a circular milling operation with tool radius compensation, I can only chose between two approach macros: "Predefined" or...
Thanks Awerby, the problem is that both solutions are quite big and the hacksaw I think takes too long. What abaut a circular saw like this one

Dear all,
I have just built my cnc milling machine and I want to start to mill the first parts. I already have some aluminium bars and plates, but I need to cut them. Which kind of tool do you...
I have done a test: I have put all the switches relative to the microstepping seeing in ON position, that is the only combination not present I the manual and like that the controller moves the...
I would prefer full step because it allow faster rotation and also more torque.
I had already read the manual, but both my questions are not solved there...
Dear all,
I have a DM542T driver and I am not sure about the settings to choose.
In the settings of microstepping is not explained how to set it with full step. I think to do it I have to put all...
Said that I would prefer to use the RC filter instead that the plugin, I have read a lot of documentation and examples and it looks like that the VFD has some sort of filter, so using the PWM at high...
Dear All,
I have just bought a Huanyang VFD and I am wiring it. I have a doubt about how to control the speed, I have checked in many forums, but there are a lot of different theories, so I would...
Dear all,
I am building my first milling machine, using UC300ETH and UCBB. I have read a lot of posts about the charge pump, but it is not clear if I need it or if it is useless.
Can you help me?
Sorry, but this is my first CNC project and more I read, more I am confused.
So resuming: I have the UC300eth and I need a BOB, I think I will go for the UCBB that is the same brand as the...
Can you explain me the advantages of a ub1 that costs around 200€ versus a c10 that costs around 15€?
Hi, I have already seen that, but it is the most expensive... for me makes no sense spending more for a breakout board than for the controller.
Dear ger21, at the end I have decided to follow your advice, I will swap to UCCNC, so I have ordered a UC300eth.
Can somebody tell suggest me a breakout board to use with this controller? I have...
Hello, I am designing a 4 axis milling machine and I have some doubts about the electrincs to use.
Because the laptop I have avaible does not have any parallel port, I thin k the best choice for...
I don't have experience of harmonic, but I think they are quite difficult to machine because I imagine they have to be by steel and very thin too...
Thanks Dharmic, for your feedback. I have looked for arminc drives but they look very expensive. So I think I can put to series of pulleys 12/60 each, so in total I can achieve a reduction of 1:25...
Dear all,
I am designing my first 5 axis CNC milling machine mainly to work aluminium. For X, Y and Z axis I have chosen Nema 23 stepper motors that provide 1.9 Nm torque and a lead screw 10x2mm....
