ELEKTOR FORUMS

Excuse my English.

Hello I have an industrial electronics company for 12 years I am electronics engineer From 1996. to buy a profiler to build electronic prototypes and small series is not very complex.

Since the machine came across problems and were more problems.

1 The assembly is complicated even for me that I have a few hours of experience in electromechanical systems. I can not believe what this machine can suffer with an amateur with no experience or technical means.

2 In the counting of material missed two late race that I had to buy for myself.

3 Once the Z axis assembly did not work reviewing all the connections, the problem is that the chip that controls the stepping motors was missing a pin. After sending several emails to support colinbus told me it had crashed and that if I wanted repair would cost 150 euros or more if he wanted a new board costs $ 300 more.
While the post came and went and I bought a chip smd in rs-amidata (22 euros) is changed and damaged by the operation.
What we do not know of colinbus chip that was so, we work with systems running anti electrostatic and before applying power to the machine connections are reviewed 3 times by different people so they can tell me that I've broken me. We are not inexperienced, and we know what happens. The most important issue to take care colinbus is not the problem.

4 more problems in Z axis, now every time you move up and down too. and decentralization of the drill.

Two problems.
1 The problem is that if you tighten the attachment of the drilling machine forces the aluminum guide giving too much slack.

2 And the other problem is that the part of union between the motor and the threaded spindle is defective and not aligned straight so that when the spindle is off turns producing oscillations in the head of the drill.

1 on the problem and are seeking solutions that colinbus happens with the case.

2 on the problem we have requested a new piece colinbus not, can take years and not know how much it would charge for that piece also sure that we have broken us.

Took almost a month with the machine and I could not make even a single plate.

Short, medium colinbus is the worst I've seen since then is the ultimate buyer at this company, its motto:
Your problem is theirs not ours. (perfect)

Software manuals are Malis.

If you send an email takes days to answer, if answer.

I do not know if something is valid for the machine or have to throw them away is not clear to me.

The machine is not bad but the company behind it is....

And of course you pay everything upfront and then we'll see

Warranty on the product, not referred to.

colinbus change its policy because it is harmful.

Greetings to all and, Patience is for these occasions.

Certainly someone can tell me what is the easiest way of center a single-sided PCB with reference to the drawing and drill colidrive in which only wants to drill.
Thank you

Hi I would like to clarify that I am not saying that the machine can not function nor say it is bad. I just say that I have the machine that does not work and that technical support does not work either. These two observations are made. Reassuring to know that there are people who work for you, but it certainly made to work if my machine is not for the help of colinbus and this should not be so.

Thank you

Hello Francisco,
Please read my comments below

1 The assembly is complicated even for me that I have a few hours of experience in electromechanical systems. I can not believe what this machine can suffer with an amateur with no experience or technical means.

We have lots of users who manage to assemble machine without any problem. I am not claiming that it is always easy but various users age 15 - 70 manage to do it.

2 In the counting of material missed two late race that I had to buy for myself.

Indeed it does happen that in some packages something is missing but when people contact me (support@colinbus.com) I make sure that their missing parts are shipped out free of charge.

3 Once the Z axis assembly did not work reviewing all the connections, the problem is that the chip that controls the stepping motors was missing a pin. After sending several emails to support colinbus told me it had crashed and that if I wanted repair would cost 150 euros or more if he wanted a new board costs $ 300 more.

All controller and power boards are shipped out and checked before they leave. In your case there was no pin missing but it was blown due to short circuit. This was very clear on the photos you send to us.

4 more problems in Z axis, now every time you move up and down too. and decentralization of the drill.

Alignment of Z-axis is known issue on the profiler but this is not something that can't be fixed. I managed to help other people build their z-axis so it should work in your case as well.

Two problems.
1 The problem is that if you tighten the attachment of the drilling machine forces the aluminum guide giving too much slack.

This can be fixed by aligning z-axis correctly

2 And the other problem is that the part of union between the motor and the threaded spindle is defective and not aligned straight so that when the spindle is off turns producing oscillations in the head of the drill.

The text here below applies for your problem above:

Z-axis is bit catchy to align but your problem is very likely in alignment.
To start with, please try to connect lead screw with motor using motor coupling but when tightening the screws do it one at the time and switch constantly between them so you get even pressure on both screws and in the same time try to keep coupling straight. This is the most common problem that when Z-axis is blocking, coupling turns eccentric. Line motor-coupling-lead screw MUST be straight otherwise all your other efforts are useless. To test everything start up with low speed, since motor is most powerful at low speeds. As speed increases the motor force decreases.
In addition check that your lead screw nut is completely straight so the lead screw does not catch any side tension when turning.


Play in the Z-ax can be avoided when mounting MPI00021 & 22 the eccentric wheels should good placed in the opening on the adjustment plates. Experience tell us that it is easily to make mistake by not inserting those wheels completely in the opening on the adjustment plate. Second problem is that by turning one of the adjustment plates completely to the side it becomes impossible to adjust the other one. Solution to this problem is, even if it sounds un-logic, to turn eccentric wheel which has no play more to inside until there is no play on the other one. In short, eccentric wheels should be equally far to the side cause turning them too much to the side you are widening the Z-ax profile and creating play. Basically just try to play with eccentric wheels and keep them more or less in the straight vertical line, not too wide and your problem will be gone. (tip - if this still does not work you could remove the adjustment plates on both eccentric wheel and you will be able to turn it even bit more to the side)
1 on the problem and are seeking solutions that colinbus happens with the case.

2 on the problem we have requested a new piece colinbus not, can take years and not know how much it would charge for that piece also sure that we have broken us.

I believe I received more than 20 different emails from you and the only one I did not answer is the last one where I was about to ask you to send me the files to inspect them since you had very weird file. From that screen shot I can't answer what could be the problem

Took almost a month with the machine and I could not make even a single plate.

I am sorry you feel that way, I was doing my best to address your issues and to help you out as I will in the future.

Software manuals are Malis.

I do not know if something is valid for the machine or have to throw them away is not clear to me.

I would ask everybody who has problem with their profiler to contact support@colinbus.com. I will do my best to address their issues ASAP. Please do understand that 100 different users are using the machine in 100 different ways and it is not always easy to figure out which way they are processing something.
If anybody has a problem with milling their files please send original files to me so we can figure out what is wrong or what they are doing wrong. When speaking of sending files, please send us (dxf, gerber, excellon) + files generated by cam package
(HPGL - plt, CBR, BFF). This way we will be able to help you faster and more efficient. Thanks to everyone for their patience and understanding. Zoran

Dear friend I agree with you Ambuman impatience is a problem, but the machine that I purchased in my case I need it for work and operations and functions, as I said in another post I want to drill pcb simply.
If Colinbus have much work I'm too busy.
The client must be met very quickly and very well at least try it on my business.
You never know which client is small or large.
Maybe a customer places an order today to 1000 € and if you do your job tomorrow may well be 10,000€ or more.

Hello again, problem opening an aluminum fixed.

Even the screws holding tight to be completely bulged out of the 2 mm bore magnets. What causes it to tighten and not totally flat open aluminum.

\_/ NO!!

|_| OK!!

The solution, smoothing the top of the screws.

I've been lucky, this time not cost me money to solving this problem, I'm very happy. )

Thanks and regards
